Title: Analysis of the effects of energy deposition on shock-driven turbulent mixing

We perform simulations of laser-driven turbulence experiments with energy deposition, modeling situations where energy is deposited in a mixing layer before or after it is reshocked. Such situations are experienced in, e.g., inertial confinement fusion capsules. We show that the timing of the energy deposition has a significant impact on the development of turbulent flow and corresponding turbulent material mixing. In particular, if the energy is deposited before the shock wave begins interacting with the mixing layer, the development of turbulence and turbulent mixing are inhibited. If, however, the energy is deposited after the shock wave has interacted with a portion of the mixing layer, turbulence generation and turbulent mixing are enhanced.
