AN EXPERIMENTAL STUDY OF THE INTERFACIAL FRICTION FACTOR FOR COUNTERCURRENT STRATIFIED AIR-WATER FLOW IN NEARLY HORIZONTAL AND INCLINED PIPES

  • Published : 1996.05.01

Abstract

The Interfacial friction factor for the countercurrent stratified air-wafer flow has been experimentally investigated in nearly horizontal and inclined pipes. The presence of the hydraulic jump may significantly affect both the flow pattern and the interfacial friction factor. The measured values of f$_{i}$ in nearly horizontal and two inclined pipes are of the same order of magnitude but the dependencies of the air and water velocities are slightly different.t.
