Reliable cooling of thermally high stressed components in the field of thrust chamber and turbine technology requires the use of more effective cooling techniques compared to the common recuperative cooling. Alternative cooling techniques basing on mass transfer through the wall such as transpiration cooling are available. For thermal design of transpiration cooled components a detailed knowledge with respect especially to the convective heat transfer behavior in the hot gas boundary layer on the porous wall is requested. This paper describes experimental investigations on this problem as well as the modeling of the measuring results by means of empirical correlations for engineering purposes.
