Description
Summary:The present numerical-prediction consideration of a bluff-body-stabilized synthesis gas/air diffusion flame notes the influence of turbulence modeling and boundary conditions on the predictions. Comparisons are made between the results of the standard k-epsilon model and a Reynolds-stress-equation model; the latter's predictions are in better agreement with measurements than those of the former; the two models predict significantly different composition and temperature levels in the recirculation bubble generated by the bluff body.
