In this study, we have seen a simple description of phenomenons which occur in axisymmetrical injector. We have see that a fuel injection velocity as 5 m/s or 20 m/s are so lower in order to obtain an acceptable outlet mixing area. But results are arguable because some numerical effects appear as diffusion or back flow. However, this study allows us to familiarize with AVBP Software and to discover some capacities of the code.
