doi:10.3969/j.issn.1000-1093.2012.03.001

Abstract

Abstract: Laser ignition technology is a new launch technology. The numerical simulation is carried out to investigate the influence of multi-point laser ignition to the pressure wave and abnormal combustion of the propellants. A two-dimensional two-phase flow model of multi-point laser ignition in a short-barrel gun is established. Numerical simulation is conducted by MacCormack predictor-corrector scheme and the movable boundary conditions are obtained by movable control volume method. The numerical calculation results are consistent with those of the experiments. It has good value for laser ignition system design.

Key words: fluid mechanics, laser ignition, numerical simulation, two-dimensional two-phase flow
