摘要：
A dynamic version of the thickened flame model for large eddy simulations (TFLES) of turbulent premixed combustion is implemented by coupling two independent codes through MPI (Message Passing Interface) running on massively parallel machines. The combustion code, AVBP, solves the usual filtered Navier-Stokes, mass fractions and energy balance equations on unstructured meshes while a second code takes advantage of the knowledge of resolved flow structures to automatically adjust the combustion model parameter from filtered resolved flow fields. This approach is tested against data from the F1, F2 and F3 pilot stabilised jet-flames experimentally investigated by Chen and coworkers. The model parameters determined dynamically are quite different for these cases, evidencing the decisive advantage of the dynamic procedure while statistical results are in good agreement with experimental data. The extra cost induced by the dynamic model is here about 20% but further optimisation remains possible. (C) 2011 The Combustion Institute. Published by Elsevier Inc. All rights reserved.
