W202 リブレットおよび毛皮面による乱流摩擦抵抗低減(WS2-1 流れの制御と抵抗低減,ワークショップ)
詳細
Drag-reducing ability of three kinds of seal fur surfaces, four kinds of PTFE (Poly-Tetra-Fluoro-Ethylene) pile surfaces, and a hybrid riblet surface was tested in a rectangular channel flow using water and a glycerol-water mixture. The pressure drop along the channel was measured in order to evaluate friction factors, i.e., drag reduction ratios in a wide range of Reynolds number conditions.
