A direct numerical simulation of the influence of a local energy release region on the development of the combustion propagation process in a high-speed flow of homogeneous fuel-air mixture (Н2 + air) is carried out. The mathematical model of the energy source describes the physical phenomena characteristic for pulsed energy supply using laser radiation. The energy supply and ignition are modeled taking into account a given kinetic scheme. The results on the spatial and temporal evolution of the ignition region are presented. The dependence of the position of the ignition region on the flow velocity is investigated.
