METHOD OF DEFINING FILTRATION PROPERTIES OF POROUS MEDIA PRODUCED BY POWDER METALLURGY Russian patent published in 2011 - IPC B01D39/00 G01N15/08

Abstract RU 2437705 C1

FIELD: process engineering.

SUBSTANCE: invention relates to design and experimental method of defining filtration properties of porous media produced by powder metallurgy. Protective and working properties of porous media produced by powder metallurgy processes are estimated to be forecast for various magnitudes of air speed, aerosol particle sizes depending upon pore sizes, fractional porosity, tortuosity and porous medium filtration layer thickness. Estimation of structural characteristics is performed with due allowance for transverse pores. Proposed is design formula for defining porous material filtration criterion.

EFFECT: higher validity of estimation, lower costs.
