Abstract
In this paper results of experiments conducted on two phase flow through porous layers formed of non heated glass particles (nominal diameter 3–19 mm) are reviewed. The porous layers were 30–70 cm deep and were formed in a 21 cm inside diameter plexiglass pipe. Experiments were conducted with water and air in both co and counter current modes. Data for the average void fraction and two phase friction pressure drop were taken. A flow regime map for two phase flow through porous media, a semi-theoretical model for void fraction, an empirical correlation for counter current flooding and empirical correlations for relative permeability multipliers under co-flow conditions are reported. The interaction between the overlying liquid layer and the porous layer under counter current flow conditions is discussed.
