Computing compressible internal flows by means of an Immersed Boundary Method

• Compressible solver coupled with Immersed Boundary Technique validated with several computational test cases.
• Specific boundary conditions for IBM: slip and injecting wall.
• Solver development opened to multiphysics.

This paper provides an Immersed Boundary Method for computing compressible internal flows. In view of future applications to combustion problems and hypersonic flows, wall-slip and wall-injection boundary conditions are implemented. A 2n-tree mesh-refinement algorithm is employed for combined accuracy and efficiency. The method and the new boundary conditions are tested with success versus well-documented test cases, by means of detailed mesh-refinement studies.
