At the ratio of clearance length to body height, C/D=0.05~0.1, the heat transfer was characterized by the reattachment of shear flow separated from the body. Furthermore, the heat transfer depended on both the reattachment flow and the separation vortex at C/D=0.15~0.2, and the side vortex induced by Karman vortex at C/D=0.25 and 0.275. The reattachment flow gives a superior effect to enhance heat transfer at low Reynolds number, but at larger Reynolds number, the side vortex induced by Karman vortex becomes more effective to heat transfer enhancement., 論文}, pages = {157--163}, title = {流路内壁面近くに置かれた鈍頭物体による伝熱促進}, volume = {70}, year = {2004} }
