Abstract

The Conditional Moment Closure (CMC), devised for turbulent combustion modelling, was implemented in the multiphysics code Alya, based on the Finite Element Method (FEM), in the frame of Large Eddy Simulations (LES) for unstructured meshes. A multi-code approach has been developed to run separately the transport equations for non-reacting variables (CFD) and the conditioned quantities (CMC) in two different meshes. The fundamental aspects of the algorithm are discussed while a new strategy for the interpolation between CFD and CMC meshes is described. The Cambridge swirling burner is analysed and simulations results are compared to measurements.
