We found that filter efficiency will increase when filter porosity and fiber diameter decreasing or filter thickness increasing. And the pressure drop has a linear relationship with filter thickness and non-linear relationship with filter porosity and fiber diameter. We also compared the simulation results with the real test results by TSI 3160. Although there are some differences, I think Ocodict can be used to predict filter effictency and pressure drop.展开更多

文摘In this paper, we discussed the relationship of filter effictency and pressure drop with the porosity, fiber diameter and filter thickness by Oeodict. We found that filter efficiency will increase when filter porosity and fiber diameter decreasing or filter thickness increasing. And the pressure drop has a linear relationship with filter thickness and non-linear relationship with filter porosity and fiber diameter. We also compared the simulation results with the real test results by TSI 3160. Although there are some differences, I think Ocodict can be used to predict filter effictency and pressure drop.
