Abstract

The flow patterns for gas-liquid two-phase flow have been experimentally investigated using "mm scale" rectangular channels. In this scale the transition of dominant forces from body forces such as the inertial force and buoyancy force to the surface force occurs. The surface force is changed in this study by coating repellent on the inner wall of the channel. The observed flow patterns are basically classified into three categories; bubbly flow, slug flow and annular flow just like those in wetted channels. The boundaries among them, however, become to depend on the wettability of the channel wall as the scale of the channel decreases.
