Heat transfer in combustion chambers

This paper is dedicated to reviewing and assessing the various models, embodied in a calculation procedure, that are employed in order to calculate heat transfer characteristics (the flux models, the Spherical Harmonics model, the Discrete Ordinate model, etc). The calculation procedure solves the governing conservation equation of mass, momentum and energy, expressed in a finite difference form, and employs a two-equation turbulence model and a reaction model. Calculated results obtained using the flux and the Discrete Ordinate models were compared with experimental data for three furnaces. The resulting agreement promises greater economy and better performance in furnaces and combustion chambers.
