Popis:	This paper describes an improved method for predicting wall temperatures in gas turbine combustors in terms of critical parameters such as scale and pressure. It is demonstrated that existing prediction techniques are not necessarily applicable to small combustors and that a good part of it is due to an imprecise knowledge of the hot gas temperatures within the recirculation, primary and secondary zones. From the analysis of new experimental data, obtained recently in the Laval Combustion Laboratory, with wall temperature measurements at three different scales of the same combustor, a new volume function was implemented in the formulation to account for scaling effects.
