Hot-Wire Measurements of the Stagnation Temperature Field in the Wake of Slender Bodies (Task 3.5 Experimental Gas Dynamics - Rest Program)

摘要

A preliminary experimental study of the stagnation temperature field in the laminar wake of a conical and a wedge model was made. The measurements were performed by means of a hotwire probe in a 20-in. diameter shock tunnel with a nominal free-stream Mach number of 16 and a stagnation temperature of 2400 K. Experimental results showing both the wake centerline stagnation enthalpy and transverse stagnation enthalpy profiles are presented. (Author)
