Abstract

The thermal heavily loaded components within the propulsion systems, require the use of effective thermal protection systems. Transpiration cooling applied to porous high-temperature ceramics is a promising technique in this regard. In this study, the velocity and the temperature distributions of turbulent boundary layers over an actively cooled porous C/C segment are studied. The description of the used experimental setup is given and the boundary layer profiles with respect to velocity and temperature distributions are presented. Furthermore, the Preston and Clauser method are introduced to conclude on the local friction coefficients. A reasonable agreement with values given in literature is indicated for cases without coolant injection, while for blowing the comparison with references is restricted to quantitative statements.
