Development of Numerical Simulation Methods for Analysis of Laser Guided Arc Discharge; Final rept. 3 Feb 2006-28 Feb 2008

摘要

Modeling of the Use of USP laser pre-ionization as a guide path for a high voltage discharge in air was addressed. The physical processes involved are complex and span many orders of magnitude in the temporal and spatial resolution that must be considered. A two dimensional simulation model was produced that treats the problem in different time regimes with suitable approximations. The theoretical models and numerical models developed are described along with some test calculations. The simulations were done on a single CPU PC workstation. Procedures were outlined for porting the simulation to a multi-node high performance computer.
