ふく射によって加熱された平板の水によるしみ出し冷却に関する研究

抄録

Transpiration cooling is known as one of the most effective cooling methods. Most papers on transpiration cooling dealt with the coolant of a plate heated by convection. In a very hot environment which requires transpiration cooling, however, the heat flux by radiation plays an important role. Very few papers focussing on this problem have been published. It has been pointed out that a liquid coolant is more efficient than a gaseous coolant because of its latent heat. In the present study, distilled water was used to cool a flat plate heated by radiation. The experimental results on transpiration cooling were compared with the theoretical ones and good agreement was found.
