Abstract

Direct numerical modeling of the effect of the local area of energy release on the development of the combustion propagation process in a high-speed flow of a homogeneous fuel-air mixture (H2+air) has been carried out. The mathematical model of the energy source describes the physical phenomena characteristic of pulsed energy supply using laser radiation. Energy supply and ignition are simulated taking into account a given kinetic scheme. The results on the space-time evolution of the ignition region are presented. The dependence of the position of the ignition region on the speed of the oncoming flow has been investigated.
