High-temperature hydrodynamics

We investigate the propagation of shock waves in heterogeneous and/or non-newtonian media, including interfaces separating different materials, and radiation-dominated flows. We are interested in hydrodynamic instabilities, vortex rings, and energy transfer in these systems. We use direct simulations of the mass, momentum, and energy equations, as well as semi-analytical modeling techniques.

Target applications include energy sciences (high-energy-density physics, inertial confinement fusion), hypersonics.
