Study in the Approach Prediction Ability of the Euler PDF Transport by Different Models of Turbulence

Abstract

The main objective of this study is the evaluation of the numerical capacity of the RANS-EPDF hybrid method, by comparing different turbulence models, with numerical simulations in a turbulent jet flame (hydrogen / air), using the method of Eulerian multi-environment transport to model the turbulence-chemistry interaction. And predict take-off height, flame ignition and extinction, as well as kinetic control of NOX species. The study was applied with three turbulence models, the modified k-e, k-e and the RSM. Numerical results are compared and discussed with experimental data. It was concluded that predictions of the modified k-e model are more credible than other turbulence models and favor more impact on the optimization of computational methods.
