Abstract
The objective of this work is to assess the performance of different turbulence models in conjunction with the flamelet model for chemically reacting flows. Numerical simulations of H2 /CH4 /N2 jet flame and CH4 /H2 bluff body flame have been performed. The emphasis is firstly on the investigation of the prediction capability of the combustion model and secondly on the study the performance of turbulence models in predicting diffusion flames. The simulation results are compared to experimental measurements of mixture fraction, velocity field, temperature and constituent mass fractions. The results indicated that the Explicit Algebraic Stress Model (EASM) performs superior and mimics most of the significant flow features.
