Equilibrium temperatures and heat-transfer rates for 0.00015- and 0.00030-inch diameter tungsten wires normal to the flow were determined throughout the Mach number range 0.5 to 2.5 with Reynolds number 0.5 to 2.5 with Reynolds number varying between the limits 18 and 144. This test range corresponds to hot-wire operation with Knudsen varying from 0.12 to 0.005 where Knudsen numbers of 0.01 and 2 define the limits of continuum and fully established free-molecule flow, respectively.
