Description

Device and method for achieving thermal nuclear fusion by ultrasonic cavitation Technical field

The present invention relates to the field of tribology and nuclear physics, and more particularly to an apparatus and method for achieving thermal fusion by ultrasonic cavitation.

Background technique

Due to the depletion of fossil energy and the increasing environmental problems caused by the large consumption of energy, nuclear fusion research, which has ended the solution of human energy problems in recent decades, has always been the top priority of scientific research in developed countries. The relatively inexpensive nuclear fusion material can be obtained by refining seawater, which is abundant enough for humans to use for hundreds of billions of years. The difficulty in achieving controlled thermonuclear fusion is how to create and maintain an extremely high temperature/high pressure environment. To solve this problem, scientists have struggled for more than half a century and built hundreds of large experimental devices around the world. But has not yet been successful.

The theoretical basis of nuclear fusion is that two light nuclei aggregate under certain conditions to form a heavier nuclei with a mass loss. According to Einstein's mass equation, the fusion process will release huge energy. The reaction conditions are to heat a plasma of a certain density to a sufficiently high temperature and to maintain a sufficiently long period of time for the fusion reaction to proceed. Since nuclear fusion plasmas are extremely hot (up to hundreds of millions of degrees), any physical container cannot withstand such high temperatures, so special methods must be used to constrain the high temperature plasma.

On the sun and other stars, the gravitational force of 10 to 15 million degrees Celsius is used to maintain the fusion reaction. The earth as a planet does not have such a large gravitational force. It can only be heated by low-density plasma. To a higher temperature (100 million degrees or more) to achieve a fusion reaction. There are currently two main ways to constrain the plasma by manual methods, namely inertial confinement and magnetic confinement.

In fact, there should be multiple ways to achieve controlled thermonuclear fusion, control the dynamic process of microcavity and the evolution of the liquid-vapor interface, and generate and maintain a very high temperature/very high pressure micro-environment environment inside the vacuole. The steam interface effect can control the temperature and pressure growth process in the bubble, that is, the constraint on the plasma behavior in the bubble until the thermonuclear fusion occurs.

Many scholars have carefully studied the phenomenon of energy accumulation in vacuoles, and determined that the vacuoles can generate extremely high temperature and extremely high pressure when compressed. At present, it is impossible to accurately measure the temperature inside the bubble in the compression process. The calculation of the temperature limit that can be achieved when the bubble is compressed is also widely known, spanning 10 ³ -10 ⁸ k.

Among them, the calculation of Wu CC shows that when the cavitation bubble collapses rapidly, the internal pressure can reach 10 ¹² atmospheres, the temperature can reach 10 ⁸ k, and the density of the material in the cavitation will reach 800kgcm ^-3 , other numerical simulation temperature Both are much lower than the calculated values of Wu CC, but they are all higher than several electron volts. More typical is the study by Suslick and Barber. Their research shows that there is a hot spot at the moment of cavitation collapse, and the temperature at collapse is >1.0×10 ⁶ k. At the same time, the calculation of Stringham shows that when the bubble collapses The plasma is formed inside. It indicates that the bubble collapsed instantly produced extremely high temperatures.

In the field of ultrasonic cavitation fusion experiments, Taleyarkhan, a scholar at the Oak Ridge National Laboratory in the United States, published a paper in Science in 2002, announcing that a DD reaction occurred through acoustic cavitation, and obtained hundreds of neutrons, causing huge in international academic circles. shock. However, this experiment has not been repeated and has not been recognized by the academic community. Suslick published a paper in PRL in 2007, claiming that 9 2.45 MeV neutron counts were obtained over 2,300 scans, but this data is difficult to distinguish from the five neutron counts on the bottom. So far, fusion studies based on the dynamics of the bubble wall control by ultrasound drive have not really been reported as successful.

An apparatus 100 for achieving thermal nuclear fusion by ultrasonic cavitation according to an embodiment of the present invention will be described in detail below with reference to FIG.

As shown in FIG. 1, an apparatus 100 for achieving thermal fusion by ultrasonic cavitation according to an embodiment of the present invention may include a liquid storage container 1, a test piece 2, an ultrasonic transducer 3, and an electric double layer electric field.

Specifically, the liquid storage container 1 may define a liquid storage chamber adapted to contain the hydrazine-containing fluid medium a. The hydrazine-containing fluid medium a such as heavy water may be placed in the liquid storage container 1, and the test piece 2 may be disposed in the liquid storage container. The vessel 1 contains the hydrazine fluid medium a.

As shown in Figure 1, the ultrasonic transducer 3 can include an associated transducer body 31 and a horn 32 that is adapted to extend into the hydrazine-containing fluid medium a of the reservoir. That is, the liquid surface of the turbulent fluid medium a is higher than the lower end surface of the horn 32, and the horn 32 is spaced apart from the test piece 2, and the horn 32 can be ultrasonically vibrated by the transducer body 31. In order to ultrasonically cavitation the cerium-containing fluid medium a to form a cavitation and drive the cavitation toward the test piece 2, that is, the hydrazine-containing fluid medium a can be cavitation under the action of the horn 32 and generate a micro-empty flow to the test piece 2. The bubble flow, and the microcavitation flow is driven by the horn 32 to approach the wall of the test piece 2.

Due to the extrusion mode effect, the cavitation will be compressed, and the internal matter of the cavitation will enter the plasma state. The plasma is confined by the liquid-vapor interface, and the control of the bubble wall dynamics process can be realized, and the interface effect is used to provide a gradually enhanced Stressful environment.

The double-layer electric field can be disposed between the ultrasonic transducer 3 and the test piece 2, and the double-layer electric field is used to accelerate the cavitation, so that the cavitation is gravitationally collapsed to achieve thermonuclear fusion. Optionally, as shown in FIG. 1 , positive and negative voltages are respectively applied to the horn 32 and the test piece 2 to form an electric field of the electric double layer, and after the air bubbles enter the electric field of the electric double layer, the approach can be obtained under the action of the electric field force. The acceleration of the wall surface of the test piece 2 causes the bubble to be compressed again, and the material in the bubble enters a high temperature plasma state.

Among them, the vacuoles with higher material density can enter the gravitational collapse state, and the bubble center will form extremely high temperature and extremely high pressure.

In short, the apparatus of the present invention can generate cavitation by ultrasonic vibration and can confine the plasma through the liquid-vapor interface, constructing a continuously enhanced pressure environment, resulting in cavitation collapse, and achieving thermonuclear fusion.

According to some embodiments of the present invention, the frequency of the ultrasonic vibration may be 15 kHz to 20 kHz, the diameter of the bubble generated by the excessively high ultrasonic frequency is too small, and it is difficult to increase the density of the substance in the cavity; the bubble generated by the excessively low ultrasonic frequency If the diameter is too large, it is difficult to maintain the geometric symmetrical shape of the cavitation, causing the cavitation to collapse prematurely and fail to enter the plasma state. The frequency of the ultrasonic vibration is determined to be between 15 kHz and 20 kHz, which can improve the density of the material in the cavitation. It also helps to maintain the geometric symmetrical shape of the bubble, and controls the diameter of the bubble to be on the order of micrometers, which facilitates the entry of the bubble into the plasma state.

Alternatively, the amplitude of the ultrasonic vibration may be from 10 μm to 30 μm. Thereby, the air bubbles can be sent to the electric field control range of the electric double layer, and the driving property is good, so that the air bubbles are easily moved toward the test piece 2. For example, in some embodiments of the invention, the amplitude of the ultrasonic vibration is 20 [mu]m, and the cavitation in the apparatus 100 with the ultrasonic cavitation of the parameter to achieve the thermonuclear fusion is relatively easy to move toward the test piece 2.

According to some embodiments of the present invention, the distance between the horn 32 and the test piece 2 may be 25 μm - 100 μm, so that the flow field characteristics, the technical characteristics of the horn 32, and the working efficiency of the transducer body 31 can be balanced. And so on. For example, in some specific examples of the invention, the distance between the horn 32 and the test piece 2 may be 50 μm, 75 μm, or the like.

As shown in FIG. 1, the horn 32 and the test piece 2 can be respectively connected to the DC power source 4, and the positive and negative voltages are respectively applied to the horn 32 and the test piece 2 to form an electric double layer electric field, so that the bubble is obtained. The acceleration of the wall surface of the test piece 2 is again compressed, so that the material in the bubble enters the high temperature plasma state.

Optionally, the voltage of the DC power source 4 is 8V-30V. Thereby, the electric field strength of the electric double layer can be increased under the premise that electrolysis of the ruthenium-containing fluid medium a does not occur, and the electric field strength of the electric double layer can be increased to 10 ⁸ v/m.

According to some embodiments of the invention, the test piece 2 may be made of a Group V material.

Alternatively, the test piece 2 may be made of ruthenium or iridium. The dielectric constant of germanium is 27, and the dielectric constant of germanium is 41.

In some embodiments, the cerium-containing fluid medium a may contain a surfactant, the surfactant may be an anionic surfactant or a nonionic surfactant, and the non-polar end of the active molecule of the surfactant is located in the gas phase. The polar end is in the liquid phase. Thereby, the surfactant can be used to reduce the interference between the cavitation and the cavitation and between the cavitation and the wall surface of the test piece 2, thereby preventing the cavitation from collapsing before collapse. Alternatively, the surfactant may be sodium lauryl sulfate or dodecyl sulfonic acid. Sodium or Tween20.

Advantageously, the amount of surfactant added is from 1 mmol/L to 5 mmol/L. Insufficient addition of surfactant will cause a large number of vacuoles to collapse. Excessive addition will reduce the zeta potential of the cavitation and the electrode potential of the workpiece, resulting in the cavitation being unable to be affected by the electrostatic force of the electric double layer providing sufficient acceleration, ie too low addition. The amount will reduce the anti-interference ability of the cavities, and the excessive addition will cause the surfactant to form micelles, which will also reduce the anti-interference ability of the cavities. By adding 1mmol/L to 5mmol/L of surfactant, the vacuole can have superior anti-interference ability.

The invention also discloses a method for achieving thermal nuclear fusion by ultrasonic cavitation.

As shown in FIG. 2, the method for achieving thermal fusion by ultrasonic cavitation according to an embodiment of the present invention may include the following steps: treating the cerium-containing medium by ultrasonic vibration to ultrasonically cavitation of the cerium-containing fluid medium to form a cavitation; Ultrasonic vibration drives the bubble to move toward the test piece; the electric double layer electric field is used to accelerate the bubble, so that the cavity is gravitationally collapsed to achieve the thermal fusion.

Specifically, a low-pressure environment is first generated in the ruthenium-containing fluid medium by ultrasonic vibration. When the pressure is lower than the saturated vapor pressure of the ruthenium-containing fluid medium, a large amount of micro-cavitations are generated in the ruthenium-containing fluid medium to form a micro-cavitation flow.

Then, the ultrasonic vibration is used to drive the bubble toward the test piece. According to the effect of the squeeze film, the bubble is compressed in the pressure field formed by the wall surface, and the plasma is restrained by the liquid vapor interface to realize the control of the bubble wall dynamic process. The mechanical relationship between the substances in the vacuole is transferred from the low-temperature plasma state of the short-range force balance between the molecules to the equilibrium pressure formed by the Coulomb force, the radiation pressure formed by the particle motion, and the comprehensive pressure formed by the bubble wall. Low temperature plasma state.

Finally, the double-layer electric field is used to accelerate the cavitation, and finally enters the electronic degenerate state under the constraint of the interface sheath, which generates extremely high temperature and extremely high pressure. After the bubble center generates extremely high temperature, particles will be emitted, destroying the electron degeneracy pressure. The relationship between gravity and gravity enters the gravitational collapse state. When the bubble center temperature reaches the convergence sub-tunneling condition, there will be neutron emission, and the vacuole enters the thermonuclear fusion state to realize the thermonuclear fusion.

Therefore, the method of ultrasonic cavitation according to the embodiment of the present invention realizes the method of thermal fusion, generates bubbles based on ultrasonic cavitation, and confines the plasma through the liquid-vapor interface, thereby realizing the control of the bubble wall dynamic process and promoting the bubble. The mechanical relationship between the internal materials is balanced by the low-temperature plasma state of the short-range force balance between the molecules to the equilibrium pressure formed by the Coulomb force, the radiation pressure formed by the particle motion, and the comprehensive pressure formed by the bubble wall, entering the high-temperature plasma state, and finally Under the constraint of the interface sheath, it enters the electronic degenerate state, which generates extremely high temperature and extremely high pressure. The cavity is gravitationally collapsed, and the bubble center can continuously emit high-energy neutrons to achieve thermal fusion.

According to some embodiments of the present invention, the method for achieving thermal fusion by ultrasonic cavitation may further comprise adding an anionic surfactant or a nonionic surfactant to the hydrazine-containing fluid medium, wherein the non-polarity of the active agent molecule The sexual end is located in the gas phase, and the polar end is in the liquid phase, so that the surfactant can be used to reduce the interference between the cavitation and the cavitation and between the cavitation and the wall surface of the test piece to prevent the cavitation from collapsing before collapse.

According to some embodiments of the present invention, the frequency of the ultrasonic vibration may be 15 kHz to 20 kHz, the diameter of the bubble generated by the excessively high ultrasonic frequency is too small, and it is difficult to increase the density of the substance in the cavity; the bubble generated by the excessively low ultrasonic frequency If the diameter is too large, it is difficult to maintain the geometric symmetrical shape of the cavitation, causing the cavitation to collapse prematurely and fail to enter the plasma state. The frequency of the ultrasonic vibration is determined to be between 15 kHz and 20 kHz, which can improve the material in the cavitation. The density, which is also conducive to maintaining the symmetrical shape of the bubbles, controls the diameter of the bubbles to the order of micrometers, which facilitates the entry of the bubbles into the plasma state.

In some embodiments, the amplitude of the ultrasonic vibration may range from 10 [mu]m to 30 [mu]m. Thereby, the bubble can be sent to the electric field control range of the electric double layer.

Alternatively, the electric field strength level of the double layer electric field may be 10 ⁸ v/m, and the voltage of the direct current power source is 8V-30V. Thereby, the strength of the electric field of the electric double layer can be improved under the premise that the ruthenium-containing fluid medium does not undergo electrolysis.

According to some embodiments of the invention, the test piece is made of a Group V material. The surface of the group V material has a high electrochemical window width, and the physical properties of the group V material are used to form an electric double layer electric field in the heavy water to provide an electric field force for the bubble to approach the wall surface of the test piece.
