On calculation of emission from axisymmetrical diphase mediums with thermal nonequilibrium of phases
We describe here a technique for calculating the intensity of radiation from heterogeneous products of combustion in nozzles at conditions of thermal nonequilibrium between the condensate particles and the gas phase. In order to solve the radiative transfer equation, use is made of the Ð3-approximation by the spherical harmonics method in two-dimensional definition; the irregularly-shaped domain of integration transforms into the rectangular one. Also presented are some data of calculations performed.
