Paper Abstract

The results of the investigations of turbulent fluctuation influence on heat radiation of hydrocarbon fuel combustion jets are presented. These results show that temperature fluctuations are one of the basic factors forming radiation fields on non-reactive jets. The approach used is based on optically thin pulsation approximation that allow to account for temperature fluctuation contribution using local averaging of optical characteristics in radiation transfer equation. Such averaging may be completed using model probability density functions (PDF) of temperature and concentration. Several PDF models were verified on the basis of measured and calculated jet IR radiance comparison.
