Description

A device for computer room CFD simulation through BIM

technical field

The invention relates to a simulation device, in particular to a device for performing CFD simulation of a machine room through BIM.

Background technique

BIM (Building Information Modeling, or Building Information Modeling) is another important computer application technology that appears in the engineering construction industry after CAD (Computer Aided Design) technology, and is triggering an unprecedented revolution in the construction industry. This technology uses digital modeling software to improve the efficiency of project design, construction and management, and brings great added value to construction companies that adopt this technology.

CFD software (Computational Fluid Dynamics, CFD for short). CFD is the product of the combination of modern fluid mechanics, numerical mathematics and computer science, and is a fringe science with strong vitality. It uses computer as a tool and applies various discrete mathematical methods to conduct numerical experiments, computer simulations and analytical research on various problems in fluid mechanics to solve various practical problems. CFD has developed rapidly in the past 20 years. In addition to the solid material foundation provided by the development of the computer hardware industry, it is also mainly due to the relatively large limitations of both analytical and experimental methods, such as the complexity of the problem. However, the CFD method has the advantages of low cost and the ability to simulate more complex or ideal processes. CFD software that has passed a certain assessment can broaden the scope of experimental research and reduce the costly experimental workload. Using a computer to perform a numerical simulation of a phenomenon under given parameters is equivalent to conducting a numerical experiment. In history, there have been examples in which new phenomena were first discovered by CFD numerical simulation and then confirmed by experiments. CFD software can generally launch a variety of optimized physical models, such as steady and unsteady flow, laminar flow, turbulent flow, incompressible and compressible flow, heat transfer, chemical reaction and so on. For the flow characteristics of each physical problem, there is a numerical solution suitable for it. Users can choose explicit or implicit difference formats in order to achieve the best in terms of calculation speed, stability and accuracy. CFD software can conveniently exchange values, and adopt unified pre- and post-processing tools, which saves the repetitive and inefficient labor invested by scientific researchers in computer methods, programming, and pre- and post-processing. The main energy and wisdom are used to explore the physical problems themselves.

Shanghai Disaster Recovery Center is one of the three centralized information system disaster recovery centers built by State Grid Corporation of China. This project involves many specialties, complex equipment systems, tight construction schedules, and high requirements for cost control of materials and labor. During the construction of the project, the following problems mainly existed:

(1) The disaster recovery center has a lot of equipment and complex systems, and the direction of pipelines in a limited space is very complicated. Because traditional CAD drawings use two-dimensional methods for design and drawing, there are inevitably direct collisions between equipment, pipelines, and structures. In the past, These tasks need to be comprehensively coordinated by the construction company and the design unit at the construction site, which has a negative impact on project schedule and cost control.

(2) The construction schedule of the disaster recovery center is very tight, and the team involved in the project is complex. This requires strong management and control of the construction schedule, construction system design, and personnel cross-construction on the construction site.

(3) The investment in the disaster recovery center is strictly controlled. However, due to the large number of equipment and complex systems, the statistics of equipment and material engineering quantities that account for an important proportion of the project cost often refer to the estimated budget data provided by the design unit and the construction unit. As the owner, there is no effective management tools.

(4) The disaster recovery center is a data center, the reliability of its related infrastructure is directly related to the normal, continuous and stable operation of the IT service system. Efficiency reduction or failure of any part will lead to a reduction in the availability of IT services, ranging from poor access to information to causing various unpredictable major losses. As the first line of defense to ensure the availability of the data center - "centralized monitoring" can quickly help the disaster recovery center achieve the goal of "high availability".

In view of the above main problems, it is urgent to carry out targeted research to improve the level of project management and effective monitoring capabilities, and solve the problems in construction.
