DES simulation of separation control for flow over hump

Abstract eng:
Article deals with numerical solution of the separation control using Detached Eddy Simulation turbulence model. Numerical computation was done using commercial code Fluent. Vortex structures was visualized from the numerical solution. The strong influence of side walls to the character of the flow field is visible. The effect of the flow control was observed. Computed flow field is compared with experimental data obtained from hot wire measurement in the traversing plane. Significant deviations between numerical simulation and hot wire measurement are found. Numerical simulation of the three dimmensional flow controlled flow field is still challenge for present CFD.
