### Abstract

A promising approach to the control of wall-bounded as well as free shear flows, using synthetic jet actuators, has received a great deal of attention. CFD code WIND is a product of the NPARC Alliance, a partnership between the NASA Glenn Research Center (GRC) and the Arnold Engineering Development Center (AEDC). Explicit viscous terms are computed employing the second-order central differencing and the convection terms are discretized using the third-order accurate Roe upwind algorithm. The time-implicit convection terms are computed using an approximate factorization scheme with four-stage Runge-Kutta time stepping. For three-dimensional unsteady flows, the Spalart detached eddy simulation (DES) model is also available. This reduces to the standard Spalart-Allmaras model near viscous wall, where the grid is fine and has a large aspect ratio; it acts like a large eddy simulation (LES) model away from the boundary, where the grid is coarser, and has an aspect ratio of order one. The long-time averaged, flow-field results are able to capture the global nature of the velocity fields. © 2007
