ON THE SHEAR STRESS AT THE INTERFACE AND ITS EFFECTS IN THE STRATIFIED FLOW

Toshio Iwasaki

Abstract


At the moderate velocity of the pure water which lies on the quiet salĀ£ water stable internal waves appear at the interfac in the stratified flow, and these waves will break and violated surface will arise if the velocity of the pure water may be increased. In this phase of phenomena the shear stress at the interface has the most important part. However observed aalues of this shear stress have not been reported in the systematic style. Experiments have been conducted in our laboratory since i960. Some theoretical considerations could be served to get an empirical equation on the mterfacial shear using experimental results and data presented by other researchers.
