Original Abstract

This paper presents a preliminary study which aims to compare wall heat fluxes in swirling combustion of fuel-oil in large-scale combustor obtained both by experimental measurement and computer simulation. Prediction of wall heat fluxes is of crucial importance when designing industrial furnaces. The first part of the paper presents the experimental facilities and the method used to gather and analyze the measured data. In the second part a Computational Fluid Dynamics (CFD) simulation of the spray combustion is performed. The liquid phase is modelled using Discrete Phase Model (DPM) and the flow is solved by Reynolds-averaged Navier-Stokes (RANS) models. Various submodels are used to account for turbulence, radiation, fuel atomization and evaporation. The obtained results, i.e. means of wall heat fluxes, are finally compared with the experimental data and deviations together with possible explanations and improvements are discussed. Results show discrepancies which need to be addressed in future research.
