Reacting two-phase flows attract particular interest because of their applicability to pulse detonation engines. Use of laser pulse allows to create desired temporal and spatial distributions of ignition centres and to perform a homogeneous ignition within the sub-microsecond interval. 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 modelling are developed and validated. Laser-induced detonation in particulate systems is studied, and possibilities of the new methodology are demonstrated.
