摘要
The counter gradient transport phenomena on momentum, energy and passive scalar in turbulent flows were studied by use of the single response friction for TSDIA. As a result, models that can describe qualitatively the phenomena are obtained. Then the results are simplified by use of the internal range theory, and the results for lower degrees agree with results of predecessor. Finally the counter gradient-transport phenomena in channel flow and circular wake flow are analyzed.
