Simulation analysis of filtration characteristics of fiber materials based on random algorithm

Popis výsledku v původním jazyce

In order to understand flow field evolution of fiber-based air filter, a three-dimensional model, integrated filtration efficiency and particle flow path, was established based on the random algorithm fiber air filter material. The computational hydro dynamics following the Euler-Lagrange discrete phase model was studied in gas-solid flow characteristics based on the Reynolds similarity criterion in micron fiber medium. The results show that the change in inlet velocity has a significant effect on the flow field pressure and velocity field distribution. With the increase in inlet velocity, the blocked area increases, and high-speed flow and velocity vortices are more likely to be formed in the flow field voids, and the overall velocity difference increases at the same time. The pressure loss is positively correlated with the inlet velocity. The filtration efficiency of the fiber model is relatively stable for particles with average particle size of 8-18 mm, which is 80.4%-84%, and the relationship between filtration efficiency and particle size is close to direct proportion when the inlet velocity is 2 m/s.
