Pressure drops in gas-liquid flow in a 15 cm reciprocating plate column

摘要

Time-averaged pressure drops have been measured in a 15 cm internal diameter reciprocating plate column, using the water/air system under conditions of cocurrent, countercurrent and single phase (water) flow. The reciprocation fre- quency was varied from 1 to 4 Hz, while the stroke (peak to trough amplitude) was set at 2.54 cm. Two types of perfo- rated plate were used, having perforation diameters 14.3 and 6.35 mm.
