Abstract
The influence of the energy impulse-periodic action on the structure of the hydrogen-air mixture flow in a channel for going from the regime of diffusion combustion of the mixture to pseudojump-like combustion has been investigated. Experiments were carried out in a rectangular channel with sections of variable and constant cross-section. The energy input was controlled with the aid of a heat-gas-dynamic pulse generator in which a hydrogen-air mixture was burned. The intensity and regimes of combustion were determined by the flame radiation in the ultraviolet spectral region and static pressure measurements. In the course of experiments, the possibility of going from diffusion to pseudojump-like combustion under periodic energy and kinetic actions on the mixture flow has been confirmed.
