Effect of microramps on flare-induced shock – boundary-layer interaction
TL;DR: In this article, the ability of microramps to control boundary layer interaction at the vicinity of an axisymmetric compression corner was investigated computationally in a Mach 4 flow.
Journal ArticleDOI
Effect of air jet with injection pressure on the performance of mixed compression air intake
TL;DR: In this article, a computational study on the performance of mixed compression supersonic air intake has been carried out with and without air jet at various operating conditions, and the results showed that mixed compression air intake is more efficient than conventional air intake.

Effect of duct aspect ratio on normal shock wave/boundary layer interaction
TL;DR: In this article, a supersonic rectangular duct with a normal shock wave/boundary layer interaction is designed in a modular fashion so that its aspect ratio can be varied without a change in the flow geometry.
Proceedings ArticleDOI
Characterization of length scale in shock-induced boundary layer separation
TL;DR: In this article , a two-dimensional bump with a height roughly around one by third of the boundary layer thickness is introduced at the bottom wall of the wind tunnel, thus making the incoming boundary layer profile less full.

Optimal Control of Shock Wave Turbulent Boundary Layer Interactions Using Micro-Array Actuation
TL;DR: In this paper, the authors demonstrate the viability and economy of Response Surface Methodology (RSM) to determine optimal designs of micro-array actuation for controlling the shock wave turbulent boundary layer interactions within supersonic inlets and compare these concepts to conventional bleed performance.

Corner effect and separation in transonic channel flows
TL;DR: In this article, it was shown that the effective aspect ratio of an experimental facility (defined as δ * /tunnel width) is a critical factor in determining when shock-induced separation will occur.
