This work investigates the following solvers: OpenFOAM (open-source), SU2 (open-source), Star-CCM+ (commercial), and Fluent (commercial). A turbulent flat plate and wedge case at various supersonic and low-hypersonic conditions, with and without wall cooling, are used as canonical representations of realistic aerospace flow configurations. Using standard Reynolds Averaged Navier-Stokes (RANS) turbulence approximations, the canonical flows are modeled with each solver and compared, where possible, to the experimental or numerical results. Despite the grid converged simulations, notable variations in kinematic and thermodynamic profiles are observed which are quantified in the present work.
