Numerical Study of the Influence of Turbulent Diffusion Coefficients and Turbulent Prandtl Number on the Reactive Flow Simulation in a Combustor

The influence of the k –ε–RNG model parameters is studied in terms of simulation of processes in the combustor with the gas oxygen and methane inside including the conjugate heat transfer with the wall. A sufficient influence of the empirical diffusion coefficients of turbulence model on the reactiv...

Description
Summary:The influence of the k –ε–RNG model parameters is studied in terms of simulation of processes in the combustor with the gas oxygen and methane inside including the conjugate heat transfer with the wall. A sufficient influence of the empirical diffusion coefficients of turbulence model on the reactive flow simulation is observed. Recommendations for the choice of the turbulent diffusion coefficients and the turbulent Prandtl number are provided.
