高温鋼片の温度平坦化のための基礎研究 : 第3報,上壁を有する乱流衝突噴流熱伝達の特性

Concerning the flattening of temperature distribution of a steel slab, the characteristics of local heat transfer due to impingement of a confined turbulent two-dimensional air jet on a heated surface have been conducted experimentally for a jet Reynolds number up to 20 000, for 6 heated surface-slot nozzle spacings and for 3 heated side surface-porous plate spacings. It was found that the spanwise heat transfer exhibits two or three local maxima. Nusselt number at the stagnation point was constant for the dimensionless spacing 1
