Abstract
Combined convective and radiative heat transfer governs the heat load on the combustor wall. This paper reviews engineering simplified models and more advanced ones. The latter ones are based on CFD approaches and a variety of methods to solve the radiative transfer equation. The principles of heat transfer in the combustor including the cooling aspects are briefly described. Details of the advanced modelling procedures are outlined and some results are discussed. Keywords: heat load calculation, gas turbine combustor, radiation, convection, turbulence, combustion, soot. 1 Introduction Several important parameters such as pattern-factor, emission of pollutants, combustion efficiency, and liner strength and stress, are coupled with the heat transfer in the combustion chambers. Heat from hot gases is transferred by radiation and conve
