Structure of the Mesh

One of the pedagogical interest of this project was to get familiar with the unstructured data format. Indeed we have used an unstructured mesh provided by F.Ducros (Our supervisor during this work, from CERFACS Toulouse).

The mesh is symmetrical towards the horizontal axis. It will be useful in the calculation of Mass flow inside the engine, because we could easily define a vertical section.

The grid is not enough refined near the walls, the viscous effects due to the adherence cannot be computed. We will solve the Euler equations on the domain, and we consider we can neglect the effects of the viscosity on the mass flow calculation.
