Influence of corner angle in streamwise supersonic corner flow

We use the Reynolds-averaged Navier–Stokes (RANS) equations with a full Reynolds stress model (RSM) to study effect of corner angle in supersonic flow. RANS data are compared reference direct numerical simulation fully developed square duct flow, which support predictive capability secondary flows from Stress-ω RSM. then carry out parametric by changing range θ = 45 °– 135 °, focusing on mean streamwise and The maximum strength about 0.015 u ∞ occurs for 90 is similar what found ducts. Secondary eddies have approximately unit aspect ratio, they maintain their shape different angles translating direction parallel closest wall. As result, position vortex center can be described simple geometrical transformation wall-parallel coordinate. find that small responsible locally relaminarization flow at corner, but otherwise velocity profiles transformed according van Driest following canonical law-of-the-wall.
