This paper describes a detached-eddy simulation (DES) for the flow over a wall-mounted hump. The Reynolds number based\r\non the hump chord is Rec = 9.36 Ã?â?? 105 with an in-let Mach number of 0.1. Solutions of the three-dimensional Reynoldsaveraged\r\nNavier-Stokes (RANS) procedure are obtained using the Wilcox k - ? equations. The DES results are obtained using\r\nthe model presented by Bush and Mani and are compared with RANS solutions and experimental data from NASAââ?¬â?¢s 2004\r\nComputational Fluid Dynamics Validation on Synthetic Jets and Turbulent Separation Control Workshop. The DES procedure\r\nexhibited a three-dimensional flow structure in the wake, with a 13.65% shorter mean separation region compared to RANS and a\r\nmean reattachment length that is in good agreement with experimental measurements. DES predictions of the pressure coefficient\r\nin the separation region also exhibit good agreement with experiment and are more accurate than RANS predictions.
