In a continual push to improve the operability and performance of combustion devices, high-fidelity simulation methods for turbulent combustion are emerging as critical elements in the design process. Multiphysics Large Eddy Simulation based methodologies can accurately predict mixing, study flame structure and stability, and even predict product and pollutant concentrations at design and off-design conditions. Cascade Technologies’s multiphysics variable density flow solver VIDA™ provides an enabling technology for high-fidelity Large Eddy Simulation of mixing and reacting flows in low-Mach number regimes. VIDA combines high-fidelity gas phase flow simulations with phase interface tracking, as well as detailed models for droplet breakup and evaporation, and it has been applied to a wide variety of mixing and reacting flow problems including combustor problems with very complex geometries.
