Modeling of Turbulent Premixed Flames Using Flamelet-Generated Manifolds
2017Efficient and reliable numerical models have become important tools in the design and optimization process of modern combustion equipment. For accurate predictions of flame stability and pollutant emissions, the use of detailed comprehensive chemical models is required. This accuracy, unfortunately, comes at a very high computational cost. The flamelet-

Laminar Flamelet Model (LFM) [1–2] represents the turbulent flame brush using statistical averaging of laminar flamelets whose structure is not affected by turbulence. The chemical non-equilibrium effects considered in this model are due to local turbulent straining only.

Modelling of premixed counterflow flames using the flamelet-generated manifold method
Combustion Theory and Modelling, 2002In the recently introduced flamelet-generated manifold (FGM) method the ideas of the manifold and the flamelet approach are combined: a manifold is constructed using one-dimensional flamelets. In this paper the effect of flame stretch on theaccuracy of the FGM method is investigated. In order to isolate the effect of flame stretch, premixed methane/air

Modeling non-premixed laminar co-flow flames using flamelet-generated manifolds
Combustion and Flame, 2012The goal of this paper is to investigate the ability of the flamelet-generated manifold (FGM) approach for the numerical simulation of multidimensional laminar non-premixed flames. FGM’s constructed from premixed and non-premixed one-dimensional flamelets have been applied to a laminar methane flame in a co-flow of air.

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 ...

The recently introduced Flamelet Generated Manifold (FGM) method has proved to be an accurate and efficient reduction method for the modelling of premixed flames. The FGM method uses a chemical library based on one-dimensional unstrained premixed flames to model the chemistry of a multi-dimensional flame.

Predicting NO Formation with Flamelet Generated Manifolds
2009With the increasing tightness of emission limits, models for pollutant formation become more and more important. Steady flamelet models have proven to be very efficient methods to model combustion. However, formation of nitrogen oxide and soot are relatively slow chemical processes, which cannot be assumed in quasi-steady state and therefore need ...
