Radiation-hydrodynamics, the coupling of thermal radiative transfer and hydrodynamics, plays a crucial role in many multiphysics applications, including inertial confinement fusion, high-energy-density physics experiments, and several astrophysical phenomena. Accurate modeling of these systems requires accounting for the effects of material motion on radiation transport, which at sub-relativistic velocities can be described through an O(v/c) treatment. In practice, simplified material-motion corrections are often employed to reduce computational complexity while preserving key properties of the full O(v/c) equations, but the accuracy of these approximations in predicting radiation–material energy and momentum exchange has received limited investigation. In this presentation, we review the derivation of the O(v/c) transport equation and discuss an efficient solution scheme for the O(v/c) radiation-hydrodynamics equations that will enable direct comparison with solutions obtained using simplified material-motion corrections.
