Abstract

The objective of this work is to assess the performance of different combustion models in predicting turbulent nonpremixed combustion in conjunction with the k  turbulence model. The laminar flamelet, equilibrium chemistry, constrained equilibrium chemistry and flame sheet models are applied to simulate combustion in a CH4/H2 bluff-body flame experimentally studied by the University of Sydney. The computational results are compared to experimental values of mixture fraction, temperature and constituent mass fractions. The comparison shows that the laminar flamelet model performs better than other combustion models and mimics most of the significant features of the bluff body flame.
