Résumé

It is expected that the transpiration cooling effectiveness using liquid coolant is much higher than that using gaseous one because of the latent heat of evaporation. In this paper, the transpiration cooling using water as a coolant is experimentally and theoretically investigated and the comparison of the both results are discussed. For simplicity, one-dimensional phenomenon is assumed in the theoretical study. In general, the predicted transpiration cooling effectiveness agrees well with the measured one, but the measured results are higher than the predicted ones. Little effects of the main stream velocity and temperature, and the water level on the transpiration cooling effectiveness were observed in the range of the present study.
