Abstract:Aiming at the problem that large-scale field test of aerosol will cost a lot of manpower and material resources, and the harmful effects of aerosol itself are uncontrollable, in order to improve the efficiency of the test and ensure the safety and reliability of the test, in this paper CFD software is used to control the formation of aerosols and the safety and reliability of the test. The diffusion process is studied by computer simulation. Firstly, we conduct numerical simulation research on the formation process of aerosol mixture, builds physical and mathematical models to simulate the formation process of liquid aerosol, and simulate the interaction among multiple aerosol sources by adding the number of aerosol injectors. The aerosol is then continuously injected into the room-sized model, and the concentration of the dispersed aerosol is allowed to decay naturally for a period of time. The results show that when the liquid aerosol enters the environment, it diffuses in the environment and accumulates in the middle and lower parts; when the ambient pressure increases, the diffusion rate will decrease. The analysis and simulation results show that the liquid aerosol model can be used as an effective tool to reasonably analyze the effect of liquid aerosol diffusion.
