Краткое описание
In this work, a new SGS model for the filtered scalar flux vector is presented to develop Large Eddy Simulation (LES) of non-premixed, turbulent reacting liquid flows. To cover different reaction regimes, this work uses different ways to approach the chemical source term. To assess the accuracy of the SGS models proposed, the results are first provided for a non-reacting jet in (water) channel flow showing a very good agreement with experimental data. Then the LES was applied to a gas mixing layer flow with chemical reactions. LES computations are well compared with DNS data. Thereafter the first results in a confined impinging jets reactor are presented and discussed.
