Abstract EN
A computational-based investigation has been carried out to examine the heat transfer effects of normal and tangential blowing on blunt surfaces exposed to high Mach number flows.
Experimental results from such studies where a controlled outflow is imposed upon a surface under hypersonic conditions are few and far between.
Simple 3D axisymmetric configurations supporting flat front surfaces suited to accommodate uniform frontal flow or round-nosed conical bodies with a stepped shoulder to provide uniform parallel flow to the conical surface were selected from a NASA experiment for validation purposes.
Uniform outflow of 0.55 to 1.0 kg/s was applied in the presence of the prevailing free stream of M=6.8 to assess the extent of heat transfer rate alleviation.
The numerical simulation confirmed the experiment that the application of outflow in both cases leads to the surface heat transfer relief.
