Abstract:

A flared 10-deg semiangle axisymmetric body was tested at Mach 6, 8, and 10 in the von Karman Gas Dynamics Facility to investigate the effect of model wall temperature on the existence of laminar flow separation and reattachment. The results consisted of longitudinal surface pressure distributions obtained at zero incidence. By varying the stagnation pressure, the influence of the free-stream Reynolds number on the extent of flow separation was also investigated. Extensive measurements were made at Mach 8 for Reynolds numbers based on centerbody diameter ranging from about 0.05 to 0.29 million and at wall temperatures from about 0.1 to 0.8 times the free- stream stagnation temperature.
