V・II-5平行平板流路内に設置した円柱周辺の流れと伝熱面上の温度分布の可視化

Three dimensional flow around a cylinder settled vertically in a parallel channel was visualized by a 'Pearl pigment' method. Horseshoe-vortexes in front of the cylinder and alternating vortexes downstream the cylinder were observed. The temperature distributions around the cylinder were visualized by using a thermosensitive liquid crystal layer painted on the heat transfer plane of the channel.
