The accurate prediction of laminar-turbulent transition in hypersonic boundary layers is a critical part of the aerodynamic heating analyses on hypersonic vehicles. Despite decades of extensive research, the prediction of hypersonic boundary-layer transition is still mostly based on empirical correlation methods or the semi-empirical n e method because a number of physical mechanisms leading to...

Modulating the boundary layer velocity profile is a very promising strategy for achieving transition delay and reducing friction of plate. By perturbing flow with counter-rotating vortices that undergo transient, non-modal growth, streamwise-aligned streaks are formed inside layer, which have been proved (theoretical experimentally) to be robust structures. In this paper, we employ efficient nu...
