Shock wave and turbulent boundary layer interactions are phenomena encountered in high-speed flows, where abrupt pressure changes associated with shock waves impinge upon the viscous layer of fluid ...

The control of small structures and fast modes needs not only more accurate values in the commonly used dimensions (, u, T, P), but also, in fact more essentially, the controls from more dimensions.

We have found that low levels of helium injection near the leading edge stabilizes the turbulent boundary layer, apparently causing a reverse transition to laminar flow to take place. These results ...

Inlet unstart is a particularly critical issue associated with scramjets. That is the upstream displacement or disgorging of the original inlet shock system. Large flow spillage can be caused by the ...
