Experiments were conducted to measure the heat flux in the vicinity of a three-dimensional protuberance placed on a flat plate facing a hypersonic flow at zero angle of attack. The effects of flow enthalpy and height of the protuberance on the interference heating in its vicinity were studied. Evidence of disturbed flow with highly three-dimensional characteristics and heightened vorticity was observed near the protrusion. A parametric study by changing the deflection angle of the protuberance was also made. Correlations exist in the open literature for enthalpy values lower than 2 MJ / kg . This effort has yielded a new correlation that is valid for enthalpies up to 6 MJ / kg . The Z-type schlieren technique was used to visualize the flow features qualitatively for one of the flow conditions studied.
