Abstract:

Force measurements were made to investigate the effect of wall temperature on sphere drag in low-density supersonic flow. Drag data were obtained by fixing flow conditions and changing only the sphere wall temperature. A means of correlating drag data in transition flow is suggested, and its validity is assessed by applying the correlation parameter to this and several other sets of experimental data.
