Abstract: A method is described for the calculation of directional emissivity of volumes of arbitrary geometry filled with radiating, absorbing, and scattering medium. The high efficiency of Monte-Carlo simulation method based on local sampling algorithm is demonstrated. The problem of test solutions is discussed, which are used for estimating the Monte-Carlo simulation algorithms. Results are given of calculation of spectral directional emissivity of model jet of a solid-propellant engine.
