CHARACTERISTICS OF THE TURBULENT BOUNDARY LAYER WITH HEAT AND MASS TRANSFER AT M EQUALS 6.7

Abstract

Effects of air transpiration and wall temperature on turbulent boundary layer characteristics were measured on a porous flat plate at M=6.7. The velocity profile is described by a mixing length analysis, the velocity being in a form similar to the incompressible semi-logarithmic law. From this equation, the skin friction was calculated and found to agree with measurements. Heat transfer can be evaluated from Reynolds analogy, experimentally verified with and without air transpiration.
