Abstract

A countercurrent gas-liquid flow through a fixed bed of spherical particles was examined. The liquid flows along the surface of the particles and forms a thin film. The case of small gas flow rate was examined. The presence of the liquid film increased the gas pressure drop by three mechanisms. The liquid film made the apparent size of the particles larger, decreased the pore space for the gas flow and increased the apparent velocity of the gas. The excess pressure drop was examined.
