Abstract Results for the swirling, un-staged, 300 kW BERL natural gas flame have been obtained using the CFD code FLUENT/UNS. The solver is based on a fully unstructured finite volume scheme. The predictions have been compared to those obtained using the structured solver FLUENT. Some comparisions with measurements are also made. Turbulence is modeled by means of the standard k-f model. Two different models to describe the turbulence chemistry interaction have been considered: i) a conserved scalar pdf model, ii) the Magnussen-Hjertager eddy breakup model. For the first sub-model, the f3 probability density function is used, while the second uses either a single step reaction scheme or a two-step reaction scheme. Radiation is computed using the P-l differential approximation and the WSGGM (Weighted Sum of Gray Gases Model) is used to calculate the radiative properties. Comparison of velocities, temperature and species concentrations for both FLUENT and FLUENT/UNS using the conserved scalar pdf model have been made at three stations downstream of the quarl. Predictions of velocities, temperature and species using the different schemes (pdf, Magnussen single step, and Magnussen two-step) are also compared to experimental data at some stations.
