SUMMARY

Shock-driven, compressible turbulent mixing is important for many applications, including the scramjet engine. If possible, it would be beneficial if turbulence could be designed in order to enhance this mixing. An experimental study will be performed using the inclined shock tube facility at Georgia Tech to investigate the hypothesis that a signature of initial conditions persists in turbulent flows at late times. The goals of this study are to (1) understand the impact of initial conditions on energy deposition in shock-driven flows, and (2) to evaluate how initial conditions affect intermediate to late-time mixing. Laser diagnostics, including Particle Image Velocimetry and Planar Laser-Induced Fluorescence, will be utilized to quantify the velocity and density fields, respectively.
