Computational radiation hydrodynamics

This paper deals about pure hydrodynamic and radiation hydrodynamic codes developed at LUTH, dedicated to astrophysical simulations. The studied phenomena in this area are often encountered at high Mach number and in a radiation regime where no a priori assumption can be made on the radiation transfer. The radiative hydrodynamic code HADES has to can perform simulations as well as any optical depths, from smallest to highest. Validation of numerical schemes or physical assumptions will be made by laboratory astrophysical experiments. Therefore a very wide domain of initial conditions has to be accepted for computing. A succinct presentation of three codes is done, accompanied with some astrophysical applications.
