Study on Indoor Simulation Method of Atmospheric Turbulence and Aerosol Environment

Quan Wang

Abstract: The atmospheric turbulence is simulated in the laboratory using anatmospheric simulation pool, and the intensity of atmospheric turbulence can be adjusted by controlling the temperature difference between the upper and lower plates of the simulated pool. At the same time, the PM2.5 environment was simulated in the simulation pool, and the particle sensor was used to measure the concentration of PM2.5. Since atmospheric visibility is mainly affected by PM2.5, we obtained air quality data for a period of time in a certain area of Beijing, and numerically fit the relationship between the two, and obtained a regression model between the two. Theregression model was applied to the atmospheric simulation pool to calculate the visibility of the simulated atmosphere, and compared with the air quality of the Fengtai area published by the Meteorological Bureau, and the accuracy of thesimulation pool to the PM2.5 environmental simulation was tested. Based on the turbulence simulation, the simulation pool simulates the PM2.5 environment. The method is feasible and has sufficient theoretical basis. It provides a reliable indoor experimental platform for future research on laser atmospheric transmission.
