Numerical Simulation of Laser-Induced Detonation in Multi-Phase Mixtures

摘要

Simulation of interaction of laser pulse with inert and combustible gas-particle and gas-droplet mixtures plays an important role in environmental and engineering applications. The injection of metal particles with low evaporation temperature and ionization potential or liquid droplets causes optical breakdown on individual particle or droplet, and leads to drop of detonation minimum pulse energy of the mixture. The physical and mathematical models and up-to-date numerical methodology for computer modeling are developed and validated. Laser-induced detonation in aerosol systems is studied, and possibilities of the new methodology are demonstrated.
