3-D CFD Validation of an Axisymmetric Jet in Cross-Flow (NASA Langley Workshop Validation: Case 2)

An Unsteady Reynolds-Averaged Navier-Stokes (URANS) solver WIND is employed to compute the flow field of an axisymmetric synthetic jet in cross-flow. This flow field corresponds to case 2 of NASA Langley Research Center Workshop “CFD validation of synthetic jets and turbulent separation control” held at Williamsburg, VA in March 2004. Three-dimensional simulations of case 2 have been performed by employing the appropriate boundary conditions at the diaphragm of the actuator using SST, SA and DES turbulence models. The numerical simulations are compared with the experimental data; fair agreement is obtained.
