Abstract Hypersonic boundary layer transition is a hot yet challenging problem restricting the development and breakthrough of hypersonic aerodynamics. In recent years, despite great progress made by wind tunnel experiment, mechanism prediction, only partial knowledge has been gained so far. this paper, firstly, specific scenarios control are clarified. Secondly, experimental research passive a...

Abstract

The effect of low-speed, circular synthetic jets (SJ) on the turbulent transition a laminar boundary layer is studied through direct numerical simulations. SJ capability in fixating streamwise location onset analyzed terms its operation parameters (reduced frequency F + and momentum coefficient [Formula: see text]). free-stream turbulence (FST) near-wall vortical structures generated by jet as ...
