Boundary-layer transition is a problem that has plagued several generations of aerodynamicists. There are very few things about transition that are known with certainty, other than the fact that it happens if the Reynolds number is large enough. Researchers have been frustrated by the many unsolved...
Hypersonic boundary layer transition from laminar to turbulent induced by three isolated roughness elements (ramp, diamond, and cylinder) was investigated by direct numerical simulations based on finite volume formulation with high order MDCD scheme. The effects of roughness shape on the transition mechan...
The effects of surface ablation and blowing in hypersonic boundary layer transition are studied. Ground experiments that blow cold gases through a porous wall simulate only some of the surface mass-transfer effects induced by ablation on a high-enthalpy reentry vehicle, they do not simulate any of...

When an aircraft flies at a hypersonic speed, the temperature of gas inner boundary layer near the wall is so high that the specific heat is no longer a constant but dependent upon the temperature. It is necessary to consider its effect on transition location. In this paper, the transition ...
