Interfacial shear stresses have been determined for a countercurrent stratified flow of air-water in a nearly-horizontal rectangular channel based upon measurements of pressure drops, gas velocity profiles and mean film thicknesses. The interfacial friction factors of air-water flow were of the same order of magnitude as those of steam-water flow in the three-dimensional wave regime. A new dimensionless intensity of wave height fluctuation, which may be regarded as an effective roughness of the interface, was proposed. It showed that this dimensionless parameter has a unique relationship with the equivalent roughness for the gas-liquid interface calculated using the Nikuradse equation for both air-water and steam-water data. In addition, an empirical correlation of the interfacial friction factor for air-water and steam-water flows has been developed for practical application. |
