- Abstract
A mathematical model of oxygen–methane plasma combustion at pressures of 0.2−1.6 MPa has been developed with allowance for the ionization of combustion products and recombination of charged components. Positive ion concentrations in characteristic zones of the reacting oxygen–methane mixture are estimated under the assumption of ambivalent diffusion. Distributions of self-consistent electric field and generated electric charge along the channel are determined. Results of modeling of the levels of electron and ion concentrations in the flame agree with the well-known experimental data obtained by probe methods under operation conditions of a model liquid-propellant rocket engine.
