Computational assessment of the effect of nozzle geometry on the performance of gas-puff plasma radiation sources

A computational assessment of the influence of nozzle geometry on radiative performance of double-shell, gas-puff argon implosions has been carried out. Nozzle geometries fielded in experiments on Double Eagle, Decade Quad-1, and Sandia´s Z-Machine have been considered, as have nozzle designs that have not been tested experimentally. An important element of this work was the effort to benchmark a computed result against existing experimental data. The influence of grid resolution and random perturbations has also been investigated.
