94-GT-403 SPECTRAL AND TIMERESOLVED RADIATION MEASUREMENTS IN A MODEL GAS TURBINE COMBUSTOR

ABSTRACT In the context of an extensive experimental investigation of the turbulent, reacting flow in a model gas turbine combustor, the radiation emitted by the confined three-dimensional turbulent propane/air diffusion-flame has been studied. The present study comprises for the first time spectral and timeresolved measurements of the radiative intensity at different axial locations including the reaction zone, the mixing zone and the exit of the model combustor. The radiation measurements are presented together with measurements and GFD-calculations characterizing the reacting flow field. This data set is well suited for the validation of CFO-calculations including radiative heat transfer and also for studying the interaction between turbulence and radiation. NOMENCLATUR
