NON-PREMIXED SWIRL FLAME MODELLING USING THE OPEN SOURCE CFD PACKAGE OPENFOAM
要約
In this work the Sydney swirl stabilized burner for a hydrogen:methane fuel mixture is numerically modelled
using the OpenFOAM C++ library package. A non-reacting high swirl test case (N29S159) and a reacting
low swirl test case (SMH1) were investigated using Large Eddy Simulations and the Steady Laminar Flamelet
concept. For the non-reacting case the velocity field components are in very good agreement with experimental
results. For the reacting flow case the velocity components are also in excellent agreement with experimental
values, however the scalar quantities exhibit some under prediction. Possible reasons for the under prediction
are discussed.
