Experimental Validation of Large-Eddy Simulation for Swirling Methane-Air Non-Premixed Combustion
Large-eddy simulation of swirling methane-air nonpremixed combustion was carried out using a Smagorinsky-Lilly subgrid scale stress model and a presumed-PDF fast-chemistry combustion model.The LES statistical results are validated by PIV,temperature and species concentration measurements made by the present authors.The results indicate that in the present case the presumed-PDF fast-chemistry combustion model is a fairish one.The instantaneous vorticity and temperature maps show clearly the development and the interaction between coherent structures and combustion.
