In the present study, a discrete forcing Immersed Boundary Method (IBM) is
proposed for the numerical simulation of high-speed flow problems including
heat exchange. The flow field is governed by the compressible Navier-Stokes
equations, which are resolved by using the open source library OpenFOAM. The
numerical solver is modified to include source terms in the momentum equation
and in the energy equation, which account for the presence of the immersed
body. The method is validated on some benchmark test cases dealing with forced
convection problems and moving immersed bodies. The results obtained are in
very good agreement with data provided in the literature. The method is further
assessed by investigating three-dimensional high Mach flows around a heated
sphere with different wall temperature. Even for this more complex test case,
the method provides an accurate representation of both thermal and velocity
fields
