Abstract: The flow resistance analysis method of air filter based on simulation is to use computer-aided software to calculate and process the three-dimensional digital model of air filter, and modify the empirical parameters to analyze the air distribution and flow resistance value with reference significance. The method of simulation analysis saves the production cost and cycle of the actual physical sample, which has important guiding significance for the verification and optimization of multiple demonstration schemes. Based on the characteristics of simulation analysis, the air filter models with different outlet fillet sizes are calculated and analyzed. According to the comparison of the results, the change trend of air filter flow resistance with outlet fillet size is obtained, which is convenient to guide the optimization of air filter scheme.
