| Abstract: | A numerical study of a propulsive jet flow confined by bottom plane and against a flat plate is made. The Euler equations are solved using a Petrov-Galerkin finite element approach with a stream-upwind technique.The flow field details are described in both the jet exit base region and the near region of the opposite plane.The computation results are applied on a missile launching pad successfully. |
