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

A High-Order Central ENO Finite-Volume Scheme for Three-Dimensional Turbulent Reactive Flows on Unstructured Mesh

High-order discretization techniques offer the potential to significantly reduce the computational costs necessary to obtain accurate predictions when compared to lower-order methods. However, efficient, universallyapplicable, high-order discretizations remain somewhat illusive, especially for more arbitrary unstructured meshes and for large-eddy simulation (LES) of turbulent reacting flows. A ...

Towards Petascale Large Eddy Simulation of Reacting Flow

A novel computational methodology, termed “Irregularly Portioned Lagrangian Monte Carlo-Finite Difference” (IPLMCFD) is developed for large eddy simulation (LES) of turbulent flows. This methodology is intended for use in the filtered density function (FDF) formulation and is particularly suitable for simulation of chemically reacting flows on massively parallel platforms. The IPLMCFD facilitat...

Progress in the Prediction of Entropy Generation in Turbulent Reacting Flows Using Large Eddy Simulation

An overview is presented of the recent developments in the application of large eddy simulation (LES) for prediction and analysis of local entropy generation in turbulent reacting flows. A challenging issue in such LES is subgrid-scale (SGS) modeling of filtered entropy generation terms. An effective closure strategy, recently developed, is based on the filtered density function (FDF) methodolo...
