A model of the energy transport in turbulent laser plasma of porous targets

A physical-mathematical model of the interaction of high-power laser pulses with a low-density porous target has been proposed. Such a plasma is strongly inhomogeneous and turbulent. The direct computer modeling of three-dimensional (3D) vortex flows in such a plasma is a very laborious process for modern supercomputers. We have developed a single-parameter model of energy transport in a turbulent laser plasma. 2D numerical simulations have been carried out for the modeling of 'hydrothermal wave' expansion in such a plasma using the 2D Lagrange code ATLANT-C. There was good agreement between the numerical results and the experimental data from the Prague Asterix Laser System (PALS) facility. We discuss various different applications of such porous targets in modern high-energy density physics.
