| Abstract: |
| Impinging jet produced by launching missile was numerically simulated by using NND2M difference scheme which was simple structure and efficient to use The computation was based on the Navier Stokes equations The computational results were well agreement with the experimental results Then the flow structure was studied |
| Key words: Missile propulsion Engine exhaust Plume Jet enterference Numerical simulation |
