The paper present a numerical/experimental investigation of the flow field resulting around a generic vehiole controlled by means of a lateral jet in supersonic motion. The experimental data are acquired in the DLR wind tunnel TMK in Cologne. To obtain the numerical results, the 3-D viscous, turbulent, Reynolds-averaged hybrid Navier-Stokes Code TAU of DLR is used. Caloulations are made for free stream Maeh number of M∞=2.8 and various angles of attack. Several grids of varied density and structure and different Inrbulenee models are investigated. The CFD results in terms of surface pressure, normal force coefficients, and jet interaction are in good agreement with the results from wind-tunnel tests. On hand the numerical results it is shown important features of the interaction mechanisms between the lateral jet and the flow field originated by the motion of the vehicle.
