The permeability coefficient of a porous medium saturated with a gas or liquid after a confined explosion

Considerable scientific and practical interest attaches to the changes in infiltration properties of a medium produced by a confined explosion. Here the authors give results from processing experimental data obtained on a porous saturated medium after a confined explosion. The pressure difference and the fluid flow rate between different points in the medium were determined in the stationary state. These data are used as initial ones in solving the two-dimensional inverse problem for the permeability coefficient. The method of solving the problem is applied in processing experimental results obtained on a porous saturated medium after a confined explosion.
