Wall Temperature Effects on Laminar Wakes.

Abstract

An experimental investigation was made of the effects of cold wall conditions on the structure of the laminar near wake of a 7 degree half-angle right circular cone with a sharp nose at zero pitch and yaw. Free stream Mach number and Reynolds number were M=6.3 and Re=112,500 per inch. The cone was supported by a five-degree-of-freedom magnetic model suspension system. Measurements of pitot pressure and the recovery temperature of a cylindrical hot film were made in the region extending from the model base to five base diameters downstream. A time-dependent method was used in which the data were taken while an initially cold model slowly warmed up to adiabatic condition.
