Resistance of porous structures to compressible media at high pressure gradients

The current resistance of fine pored structures adaptable to throttling high tension media were examined. Experiments on flow in fine pored structures under high pressure gradients and compressibility of the medium are described. It is demonstrated that under luminous density the turbulent permeability coefficient obtains a constant value. Because of the high pressure differences the current medium discharges at the end of the throttling extension with the speed of sound and the average value of the current parameters is calculated along the throttling expansion which is extended in two phases.
