Theoretical Study on Fluid Resistance in Pores of Gasar Metal Porous Filter Material

The article lists features of Gasar metal porous filter materials and problems of sintered metal porous filter materials. A mathematical model was created on the basis of analysis of fluid resistance, used as the main evaluation index of permeability of porous materials. The formulas of fluid resistance in pores of porous materials were obtained and the advantage of fluid resistance of Gasar filter materials was theoretically proved.
