Filtered Density Function for Large Eddy Simulation of Turbulent Reacting Flows on Unstructured Meshes

Hybrid large-eddy simulation/Lagrangian filtered-density-function approach for simulating turbulent combustion

A consistent hybrid large-eddy simulation/filtered-density-function approach (LES-FDF) is formulated for variable-density low-Mach-number flows. The LES-FDF approach has been proposed as a suitable method for finite-rate-chemistry-based predictive modeling of turbulent reactive flows. Due to the large computational grid associated with LES, use of Lagrangian schemes is numerically expensive. In...

Analysis of Multiple Scalar Large-Eddy Simulation/Probability Density Function Formulation for Turbulent Spray Combustion

A large eddy simulation (LES)/probability density function (PDF) method is proposed for modeling turbulent spray combustion. The PDF method has the advantage that the chemical source term appears closed but requires models for the small scale mixing process. The transport equation for the joint-scalar PDF is high dimensional and solved using a Lagrangian technique. A stable and consistent numer...
