Abstract This paper investigates possible inherent modifications of the radiative heat source term due to the influence of turbulence in the thermal radiation field
of a gas turbine combustor flame. Adapting a flame temperature of 2000[K], COMSOL Multiphysics software was utilized to numerically simulate the
process, assuming a gray gas participating medium with absorption coefficient of 0.03[m-1]. The analysis of the results for five (5) different radial cut
sections of the simulated combustor chamber shows that turbulence-radiation interactions cause radiative heat losses from the flame, with the
divergence of the radiative heat flux having a deviation factor of 3.48, and a… More >
