Abstract

We report results of an investigation into the roles played by thermal and radiative transport in the propagation of Laser Supported Combustion (LSC) waves. We replace the volume radiation losses assumed by Raizer with detailed treatment of radiation in 19 frequency groups, the flux of each being calculated from the temperature in discrete cells along the LSC wave axis and allowed to deposit in other cells according to temperature dependent absorption coefficients for air. Calculations of LSC wave structure and propagation velocity as a function of laser intensity are compatible with available experimental data. a = c = CP = f = h = h = hi(a) = K = k = KV =
