Abstract
This present work presents the numerical experiments of compressible flow using the immersed boundary method with the multi direct forcing technic. Cartesian numerical meshes are used for non-Cartesian problems thanks to the dynamic immersed boundary method. All the implementations and simulations are carried out using an in-house computational code MFSim (Multiphysics Simulator), which allows to solve the Navier-Stokes equations in the transient three-dimensional form using block-structured mesh with local adaptability. Three cases were performed in the validation: the reflection of a shock wave in a flat plate, compressible flow over an inclined plate, and compressible flow around a cylinder. Consistent qualitative results are obtained, and corresponding quantitative results compare well with the reference results that other authors have published.
