A numerical study on the influence of forward-facing cavity length upon forward-facing cavity and opposing jet combined thermal protection system (TPS) cooling efficiency under hypersonic flow is conducted, by means of which the flow field parameters, heat flux distribution along the outer body surface are obtained. The numerical simulation results are validated by experiments and the cooling e...

A method is presented for calculating the aerodynamic heating and shear stresses at the wall for tangent ogive' noses that are slender enough to maintain an attached nose shock through that. portion of flight duringwhich heat transfer from' the botundary layer to the wall is significant. The lower entropy of the attached nose shock combined with the inclusion of the streamwise pressure gradient...
