Abstract

This research paper uses the method of the coupled volume of fluid and discrete phase model (coupled VOF-DPM) to analyse liquid-gas coaxial injector. The gas-liquid interface is resolved using a local solution-adaptive mesh refinement technique. The study is to evaluate the effect of the mass flow ratio of gas and liquid on the droplet velocity and Sauter mean diameter (SMD) at different injection times. Simulations were conducted using a coaxial injector with an airflow rate of \(9.852\times 10^{-4}\ {\text {kg}}/{\text {s}}\) and three different water flow rates: \(1.254\times 10^{-3}\ {\text {kg}}/{\text {s}}\), \(9.408\times 10^{-3}\ {\text {kg}}/{\text {s}}\), and \(3.136\times 10^{-2}\ {\text {kg}}/{\text {s}}\). The results show that droplet size generally increases over time at all the mass flow rates. The size of droplets also increases with an increase in water flow rate. However, the overall size of droplets decreases as they move from the injection plane to the outlet. The number of droplets formed also increases with a higher water flow rate. Droplet velocity increases with a decrease in the mass flow rate of water.
