MASS-TRANSFER ENHANCEMENT IN CHANNELS WITH A WAVY WALL

T. Nishimura et. al previously obtained the relations between Sherwood number and the Reynolds number for a channel with a sinusoidal wavy wall at the entrance region in the laminar and turbulant regions. Presented here is an extension to the previous study, using three types of wavy channel with geometrics same as before. Performance comparisons among these channels were carried out under equal pumping power requirements. The experiments covered the Reynolds number range from 100 to 10,000.
