Large-eddy simulation of span-periodic and three-dimensional shock/turbulent boundary layer interactions
Abstract/Contents
- Abstract
- Shock-turbulent boundary layer interaction (STBLI) remains a critical phenomena in the design and performance of supersonic and hypersonic vehicles. This investigation utilizes high-fidelity large-eddy simulation (LES) to better understand the physics involved in compression ramp STBLI. Specifically, streamwise oriented counter-rotating vortices in the recovery region and low frequency unsteadiness of the shock are explored in detail. A parametric variation on ramp angle is performed to explore the behavior of STBLI at a wide range of interaction strengths. An assessment of wall-modeled LES using a simple equilibrium wall-model for compression ramp STBLI at high Reynolds number is performed and deficiencies in the model are explored in detail. A first-of-its-kind LES calculation of a compression ramp STBLI with flow confining aerodynamic fences is performed to explore the three-dimensional aspects of this configuration including changes in the low frequency unsteadiness near the fences.
