An Investigation of Oblique Shock/Boundary Layer Interaction Control

Abstract

The objective of this work is to provide a basic understanding of the flow in the shock boundary layer interactions and of the mechanisms of their control. A parametric investigation was conducted to determine the effect of bleed configuration on the flow in the interaction region of an incident oblique shock with a turbulent boundary layer. Results of the numerical flow simulations were obtained for different slot widths, depths and slat angles over a bleed mass flow range between zero and choked conditions. The bleed results reveal a complex structure of compression expansion wave system over the bleed port entrance, and different levels of flow operation inside the slot. Code development for the implicit numerical solution of the two dimensional compressible Navier-Stokes and K- Epsilon equations was completed. The code was used in the simulation of unsteady supersonic cavity flow and the results compared with experimental data.... Shock boundary layer bleed interactions.
