Title: Scalar-Filtered Mass-Density-Function Simulation of Swirling Reacting Flows on Unstructured Grids

Abstract

The scalar-filtered mass-density-function methodology is employed for large-eddy simulation of two swirl-stabilized nonpremixed flames. These are low-swirl (SM1) and high-swirl (SMA2) Sydney methane flames, both of which have been the subject of detailed laboratory measurements. Combustion chemistry is modeled via a flamelet model for the low-swirl flame, and a detailed finite-rate kinetics model for the high-swirl flame. The scalar-filtered mass-density-function is simulated by a Lagrangian Monte Carlo method on a domain discretized by unstructured grids. The simulated results are assessed via comparison with experimental data and show very good agreement. This demonstrates the capability of scalar-filtered mass-density-function for large-eddy simulation of complex flows and warrants future applications of the methodology for large-eddy simulation of practical combustor configurations.
