Abstract
We conduct detailed velocity measurements in the turbulent boundary layer, which is developed on a rotating disk opposed to a turbulent jet perpendicularly impinged onto it. The effect of rotation is remarkable in both the skew in the mean flow and in the centrifugal force. We propose a non-dimensional parameter that correlates these two effects and classifies the velocity field. We find the modification of the turbulence structure due to the disk rotation in the increase of the normal stress component in the circumferential direction. The increases in the other stress components are found to be indirect, i.e., re-distribution from the circumferential normal stress is the source of modification in the turbulence structure.
