Radiative shocks experiments with high energy density lasers: 3D geometric effects on the radiative transfer
Abstract
High Mach number (supercritical) shock waves have been studied in laboratory experiments. Observations reveal that the radiation emitted by the shock front ionizes the medium ahead of the shock. Numerical computations of the radiation field are presented, assuming a plan parallel stationary hydrodynamic structure and considering an approximate atomic physics of the gas (xenon) in which the shock wave propagates. This result and simple analytical solutions in cylindrical symmetry are compared to 1D computations and 1D analytical solutions.
