A temperature distribution study in cross sections of axially symmetric flames

  • 19 Accesses

Abstract

A technique for determining temperature profiles and emissivities of combustion products in the cross section of a flame from experimentally measured spectral radiation intensities is considered. The optical electronic system used to investigate temperature fields is described, and results on the temperature distribution and emissivity of combustion products in the flame cross section obtained by the concentric zone method are given.
