APPROXIMATE MODEL OF THE ABSORPTION OF MICROWAVE RADIATION BY THE PLASMA FORMED NEAR AN ANTENNA-INITIATOR FOR PROBLEMS ON ANALYSIS OF COMBUSTION

Simulation of the propagation of microwave radiation through a plasma region in the presence of an initiator of a discharge has been performed. A region occupied by plasma and its conductivity were defined starting from the criterion of the balance between the integral rates of the reactions in the plasma. For determining the distribution of the strength of the electromagnetic field near an antenna-initiator with regard for the conducting region specified, the Helmholtz equation was solved. By the determined distributions of the electric field strength in plasma, the power of its Joule heating and the coefficients of the plasma-chemical reactions, averaged over the volume of the plasma region, were calculated. The results obtained are of interest for simulating the gas dynamics of combustion of fuel mixtures ignited by a microwave discharge
