4039 前縁を波形に加工した水平平板の後流特性(G05-8 境界層・はく離,G05 流体工学)  [in Japanese] 4039 Wake Characteristics of a Flat Plate with Wavy Leading Edge  [in Japanese]

The separation shear layer shedding from the trailing edge of a flat plate rolls periodically at a specific Reynolds number and makes vortex wake. The vortex wake includes three dimensional structure with longitudinal vortex and involves various phenomena of turbulent flow. The purpose of this study is to show wake characteristics of a flat plate with wavy leading edge which makes initial three dimensional disturbance in the separation shear layer, especially to analyze the relation between wavelength of span direction and turbulent characteristics.
