Abstract
Skin friction coefficients have been estimated by means of the momentum balance analysis. But It was revealed that the concordance rate of the measured values is not good. In this study, distributions of the mean velocities and fluctuating velocities in a cross section of a fully-developed flow region were measured in two ways, one by fixing the probe posture of I-, X-type probe in the streamwise direction, and the other by rotating the I-type probe. This study shows the distributions of five components of the Reynols stress in the lateral plane and symmetry plane. And the establishment of the similarity law related to the Reynols stress distribution was assumed.
