Tutorial Cfd Simulation Of Backward Facing Step
Webb4 aug. 2024 · Experimental investigations are carried out on flow over a backward-facing step in a subsonic wind tunnel. The effect of step angle and Reynolds number on reattachment length are studied and compared. The step angles considered are 30°, 45°, 60°, 75°, 90°. The effect of Reynolds number is studied by varying it over a range of … WebbKey Words: CFD; backward-facing step; Recirculation; Turbulent kinetic energy; SST k-𝜔 1. Introduction Flow over a backward-facing step is a classic fluid flow problem used to study turbulent separated-reattaching flows. Separated flow is generally observed in external aerodynamic and flow affected by an adverse pressure gradient. Webb1 juni 1994 · The flow field behind a small aspect ratio (channel width/step height = 3) backward-facing step is examined using laser Doppler anemometer. All three velocity components inside the separation region are surveyed in detail. The velocity profile just upstream of the step is laminar and two-dimensional. The velocity field reveals that the … pc bhurban honeymoon
