Boundary conditions for Euler equations at internal block faces of multi-block domains using local grid refinement
A method is developed for multiblock flow solvers based on an explicit cell-centered finite-volume scheme with adaptive numerical dissipation. By implementing the method in a 3D multiblock solver, a powerful aerodynamic analysis tool for solving the Euler equations in an arbitrary flow domain has been obtained. The ability of the flow solver to handle grid discontinuities over internal faces allows much freedom in the grid generation process. Finally, the use of local grid refinement per block offers the desired flow simulation accuracy with grids of reasonable size.
