Abstract
A modified method of gas-liquid porosimetry that can be used to determ ine the hydro- and gasdynamic parameters of porous media is proposed. The method is based on models of porous media and methods of determini ng pore-size distributions. Analysis of the electrical resistance of d isperse systems saturated with electrolyte and their pore structure ga ve expressions for the tortuosity and mean radius of capillaries as we ll as for the permeability of powder and fibrous materials.
