A new method based on stochastic modeling with the use 
of the approximation of the generalized telegraphic process is suggested 
to calculate thermal radiation of turbulent high-temperature flows. 
The computational advantages of this method are discussed in comparison 
with traditional approaches to stochastic modeling. The considerable 
effect of fluctuations of temperature and concentrations of radiating 
components on the formation of fields of brightness and intensity 
of radiation of a turbulent diffusion flame of a mixture of hydrogen 
and carbon oxide in air is demonstrated. The results of numerical 
simulation are compared with experimental data.
