A Comparative Numerical Simulation Study of Turbulent Non-premixed CO/H2/N2 Syngas Jet Flames

1 Institute of Fluid-Flow Machinery, Polish Academy of Sciences, Gdańsk 2 Gdańsk University of Technology, Conjoint Doctoral School GUT and IFFM PAS Abstract In the present work, numerical simulations of turbulent non-premixed syngas flame have been performed in Reynolds-Averaged Naver-Stokes turbulence approach using four turbulence-chemistry interaction models. To this aim, we used assumed beta PDF approach, Steady Laminar Flamelet model, Eddy Dissipation Concept and Partially Stirred Reactor model. Numerical results are compared and analysed with respect to two experiments from the TNF Workshop data sets. The most accurate predictions were obtained with the Partially Stirred Reactor model in OpenFOAM. Finally, we present a simulation of an industrial combustion chamber designed for low-calorific gas burning.
