Development of a Multi-Phase Flamelet Generated Manifold for Spray Combustion Simulations
Volume 4B: Combustion, Fuels, and Emissions, 2020Abstract In this study, a model flame of quasi-1D counterflow spray flame has been developed. The two-dimensional multiphase convection-diffusion-reaction (CDR) equations have been simplified to one dimension using similarity reduction under the Eulerian framework.

Modeling MILD combustion with flamelet-generated manifolds
2019MILD combustion has the potential to deliver high thermal efficiency with low levels of pollutant emission. In MILD combustion systems a high degree of preheating of the reactants is coupled with a high degree of dilution. Since the temperature of the reactants is above the self-ignition temperature, a complex interplay between turbulent mixing ...

Strategies for presumed PDF modeling for LES with premixed flamelet-generated manifolds
Journal of Turbulence, 2010Large Eddy Simulation is applied to a non-premixed bluff-body stabilized swirled methane-air flame of the Sydney flame series. The combustion chemistry is included via the so-called premixed flamelet-generated manifolds, being a progress variable approach based on steady premixed laminar flamelets.

An Assessment of Flamelet Generated Manifold Combustion Model for Predicting Combustor Performance
Volume 4A: Combustion, Fuels and Emissions, 2015In Rich-Quench-Lean design of aircraft gas turbine combustors, primary zone mixing is critical for emissions, flame shape, and heat transfer. From a modeling perspective, the primary zone flow prediction is largely impacted by the fidelity of the mixing model and the type of combustion model used.

Investigation of Extinction and Reignition Events Using the Flamelet Generated Manifold Model
Volume 4A: Combustion, Fuels, and Emissions, 2018Simulations for the Cambridge swirl bluff-body spray burner are performed near blow-out conditions. A hybrid stress blended eddy simulation (SBES) model is utilized for sub-grid turbulence closure. SBES blends the RANS-SST model at the boundary layer with large eddy simulation dynamic Smagorinsky model outside the boundary layer. The injected N-heptane

Flamelet Generated Manifold Strategies in Modeling of an Igniting Diesel Spray
2009A study is presented on the modeling of fuel spray combustion in diesel engines. The objective is to model igniting diesel sprays with the detailed chemistry tabulation method FGM (Flamelet GeneratedManifold). The emphasis is on the accurate prediction of auto-ignition as well as the steady combustion phase using one consistent approach.
