Abstract : The paper reports the results on an investigation of water transpiration cooling of a ceramic plate surface in a gradient dry air flow under the conditions of a turbulent boundary layer. The ambient temperature changed from 50 to 130 C, the humidity being about 1 - 3 percent. Heat and mass transfer coefficients were determined by both heat-substance balance at the wall and boundary-layer reading. As a result dimensionless formulas were obtained to describe a change in the combined heat and mass transfer rate under the above conditions. Estimated is the influence of the longitudinal pressure gradient and medium turbulization on transpiration cooling. (Author)
