Research Progress of hypersonic boundary layer transition control experiments

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, transition mechanism and transition prediction, only partial knowledge has been gained so far. In this paper, firstly, the specific scenarios of hypersonic boundary layer transition control are clarified. Secondly, the experimental research progress and mechanism of passive control and active control methods under different hypersonic transition control demands are summarized, with their advantages and disadvantages being analyzed separately. Plasma actuation is easy to produce controllable broadband aerodynamic actuation, which has potential in the field of boundary layer transition control. Hence, the following part of the paper focuses on plasma flow control. The feasibility of plasma actuation to control the hypersonic boundary layer transition is demonstrated and the research ideas are presented. Finally, hypersonic boundary layer transition control methods are summarized and the direction of future research is prospected.

Survey of control techniques to alleviate repercussions of shock-wave and boundary-layer interactions

“…Considering this, Direct Numerical Simulation (DNS), Large Eddy Simulation (LES), and even several Reynolds-averaged Navier-Stokes (RANS) models can be carried out along with the experimental study in order to capture the interaction phenomenon in detail. In addition, the hypersonic boundary layer transition control technique should be carefully looked into in order to develop future hypersonic aircraft [148].…”

Fluid Ablation Interactions on a Compression Ramp at Mach 8

“…Pieces of this highly multi-disciplinary problem has been tackled from different fronts by many research groups over the last six decades. Review articles on this past research have been compiled for studying laminar to turbulent transition [1][2][3][4] with roughness [5] as well as with ablation [6,7]. As for more recent studies from the past few years, notable contributions have been made in modeling GSI [8][9][10], performing laminar hypersonic simulations with ablation coupling [11][12][13], investigating stability and transition to turbulence in hypersonic flows [14][15][16][17][18][19] with roughness [20,21] or with blowing [22,23] and further with ablation [24][25][26][27][28], and in performing turbulent hypersonic simulations [29,30].…”

Experimental Investigation on the Control of Hypersonic Shock Wave/Boundary Layer Interaction Using Surface Arc Plasma Actuators at Double Compression Corner

“…In recent years, due to the breakthrough of high repetition, frequency, energy, and array plasma actuation technology, its great potential in the field of supersonic flow control has been reflected. Preliminary studies have been conducted on dielectric barrier discharge, plasma synthetic jet, and surface arc discharge and other forms [19][20][21][22][23][24][25][26][27], particularly surface arc discharge [20]. In recent years, in the field of supersonic/hypersonic flow control, surface arc discharge plasma actuation (especially array-type surface arc discharge plasma actuation) has highlighted the advantages of strong energy injection, high frequency response characteristics, and flush with the wall surfaces [28,29].…”
