順圧力勾配下に発達する平板境界層の乱流構造

Detailed experiments have been made for effect of the favorable pressure gradients on the law of the wall in a turbulent boundary layer. The local wall shear stress was measured with a direct measurement device. Mean and turbulent velocity profiles were measured with a hot wire anemometer. The effect of the gap between a surrounding plate and floating element will be reduced by using an appropriate floating element size. The mean velocity profile under the favorable pressure gradient is likely to be consistent with a modified log-law.
