✦ Synopsis

Two-phase, gas-liquid concurrent flow i n packed beds was investigated with the use of on air-water system and 2., 4-, and 6-in. diameter columns pocked w i t h tabular alumina porticles of 0.025 and 0.027 ft. diameters. Total pressure drop, column operating pressure, and liquid saturation were measured as functions of gas flow rote, fluid temperatures, and flow direction at several constant l i q u i d flaw rates for each column.

Correlation of the frictional pressure loss was achieved i n terms of a defined two-phase friction factor and a second correlating parameter which is a function of the liquid and gas Reynolds numbers. A viscosity correction factor was required t o extend the friction factor correlation t o include l i q u i d viscosities widely divergent from that of water.

The liquid saturation data for both upward and downward flaw were correlated i n terms of the ratio of moss flow rates of the respective phases.
