Abstract
We discuss Large Eddy Simulations of a bluff-body stabilized premixed flame (Volvo test case) with an objective to identify best practices for reacting flow simulations using fully automated meshing and Adaptive Mesh Refinement (AMR). Flamelet Generated Manifold model (FGM) and Thickened Flame model (TFM) were evaluated on different grid resolutions in this study. The geometry and boundary conditions used in the current work follows the guidelines outlined by the MVP-2 workshop. In order to identify grid independent settings, the base mesh size is varied from 3 mm down to 2 mm with further mesh refinements using AMR based on second gradients of velocity and temperature. The dynamic structure SGS model is used to close the turbulence quantities. The well-known UCSD detailed reaction mechanism with 57 species and 268 reactions for propane/air combustion is used with the FGM model. A two step global chemistry model is used in the TFM simulations in the present work. The LES results are compared against experimental data for velocity, temperature and CO mass fraction to assess the grid sensitivity on predictions with FGM and TFM models.
