MODELING OF SUFFOSION OF WATER-BEARING STRATA

UDC 533.539

A mathematical model of the sweeping-out of solid 
particles by a water flow from a porous stratum is suggested. The 
porous medium is represented in the form of two interpenetrating continua, 
one of which is connected with movable liquids and particles and the 
other with immovable ones. Corresponding expressions are obtained 
for dynamic porosity and permeability. In describing mass exchange 
between the continua, use is made of an ideal model of a porous medium 
in the form of a bundle of capillaries of different radii.
