Numerical Modeling of the Ignition of Hydrogen–Oxygen Mixtures Under Nonequilibrium Conditions

HEAT AND MASS TRANSFER IN COMBUSTION PROCESSES
First Online:
Received:

A numerical study has been made of the intensification of combustion in hydrogen-oxygen mixtures with a low-temperature nonequilibrium plasma, when the concentration of the active particles in the mixture (atoms, radicals, ions, and excited particles) is much higher than their equilibrium concentrations. Primary emphasis has been placed on the influence of higher-than-average concentrations of electronically excited O2(a 1Δg) molecules and O( 1Δ) atoms on the acceleration of the process of ignition. Electron-beam irradiation of the fuel mixture and the action of a high-voltage nanosecond discharge on it were selected for comparison of the efficiency of different types of plasma initiation of combustion.

Keywords:

combustion excited oxygen kinetic mechanism induction time electron-beam irradiation gas discharge
