ABSTRACT

Experiments have been carried out to determine the local structure of the gas-liquid flow in two corrugated channels. First, the different flow patterns were identified using a combination of visual and video observation and have been mapped on a two-dimensional graphic using the superficial velocities. The measurement of the wall shear stress by electrochemical method allowed us to give a fine description of the local two-phase flow structure.
