HOT-WIRE MEASUREMENTS IN LOW REYNOLDS NUMBER HYPERSONIC FLOWS

Abstract

Measuements were made of the heat loss and recovery temperature of a fine hot-wire at a nominal Mach number of 5.8. Data were obtained over an eight-fold range of Reynolds numbers in the transitional regime between continuum and free-molecule flow. At high Reynolds numbers, the heat transfer data agree well with the results of aufer and McClellan (J. Fluid Mech., Vol. 1, 3:276-289, 1956) which were obtained at lower Mach numbers. At lower Reynolds numbers, the results indicate a monotomic transition between continum and free molecule heat transfer laws.
