Description
Summary:The problem of an isothermic filtration of a gas-liquid mixture under pressure, exceeding the saturation pressure in a porous medium, is presented in the paper. Experimental results of the influence of the surface effect on the behaviour of the mentioned gas-liquid systems in the pre-critical area are also described here. It is demonstrated that increasing the wetting of the surface of the porous medium capillaries leads to the removal of the flow rate anomaly near the saturation pressure. Models to explain the observed effects occurring during the period of the gas-liquid mixture filtration when the pressure is higher than the saturation pressure have been offered.
