Large eddy simulation (LES) has become the de-facto computational tool formodeling complex reacting flows, especially in gas turbine applications.However, readily usable general-purpose LES codes for complex geometries aretypically academic or proprietary/commercial in nature. The objective of thiswork is to develop and disseminate an open source LES tool for low-Mach numberturbulent combustion using the OpenFOAM framework. In particular, acollocated-mesh approach suited for unstructured grid formulation is provided.Unlike other fluid dynamics models, LES accuracy is intricately linked toso-called primary and secondary conservation properties of the numericaldiscretization schemes. This implies that although the solver only evolvesequations for mass, momentum, and energy, the implied discrete equation forkinetic energy (square of velocity) should be minimally-dissipative. Here, aspecific spatial and temporal discretization is imposed such that this kineticenergy dissipation is minimized. The method is demonstrated using manufacturedsolutions approach on regular and skewed meshes, a canonical flow problem, anda turbulent sooting flame in a complex domain relevant to gas turbinesapplications.
