WebThe Thickened Flame Model (TFM) has therefore been developed to enable the simulation of such flames on relatively coarser meshes with respect to the laminar flame thickness, by artificially increasing the flame thickness without modifying the flame speed. However, the thickening of a thin flame implies the turbulent eddies at intermediate ... WebFlame surface density model . The flame surface density model is a typical topological, finite-rate combustion model applied to premixed combustion. In this type of model, one considers that the heat release in a given volume is the product of the heat release per unit flame surface, times the total flame surface present in this volume.
