摘要

The problem of ignition and combustion of a region expanding over time is considered. Combustion was initiated using a pulsed-periodic energy source. The influence of pulse frequency and flow velocity on ignition was revealed. Autoignition of a laminar hydrogen jet diluted with nitrogen in a co-current heated air flow was numerically simulated. A transient reacting mixing layer between two flows (air and fuel) with different velocities and temperatures was studied.
