Optimization Research on Numerical Simulation of Laser Propulsion

The numerical simulation of laser propulsion simulates the temporal and spatial variation characters of the flow fields accurately and that is impossible via experiment. It can simplify the research, reduce the fund of research, abbreviate the period of experiment and greatly accelerate the development of laser propulsion. This thesis adopts some serial and parallel optimization methods according to the character of laser propulsion and program language, to improve the performance of this simulation program.
