Abstract
The interference effects of side jets with supersonic cross flow for a lateral jet-controlled missile are simulated numerically. Three-dimensional NavierStokes equations along with k-w turbulence model are solved using a commercial CFD software. The simulation captures all the essential features of the flow including the forebody shock, bow-shock ahead of the injection. Effect of angle of attack, number of jets, etc. have been systematically studied. A very good agreement between computed and experimental surface pressure has been obtained. Simulation results are analyzed to find the normal forces and pitching moments for different angles of attack and number of jet injection to provide input to the control system design.
