Modeling of complex premixed burner systems by using flamelet-generated manifolds
Combustion and Flame, 2001The numerical modeling of realistic burner systems puts a very high demand on computational recources.The computational cost of combustion simulations can be reduced by reduction techniques which simplify the chemical kinetics. In this paper the recently introduced Flamelet-Generated Manifold method for premixed combustion systems is applied to laminar

The Application of Flamelet-Generated Manifold in the Modeling of Stratified Premixed Cooled Flames
Volume 4B: Combustion, Fuels and Emissions, 2014CFD predictions of flame position, stability and emissions are essential in order to obtain optimized combustor designs in a cost efficient way. However, the numerical modeling of practical combustion systems is a very challenging task. As a matter of fact, the use of detailed reaction mechanisms is necessary for such reliable predictions ...

Modeling CO With Flamelet-Generated Manifolds: Part 2 — Application
Volume 2: Combustion, Fuels and Emissions, Parts A and B, 2012Conventional Flamelet Generated Manifold (FGM) closure of the mean progress variable reaction rate assumes PDF shapes to account for turbulent fluctuations. The FGM parameters are commonly assumed to be statistically independent, and the marginal PDFs invariably require second moments, which are difficult to model accurately and have limited ...

Extending the Flamelet Generated Manifold for Soot and NOx Modeling in Diesel Spray Combustion
The Proceedings of the International symposium on diagnostics and modeling of combustion in internal combustion engines, 2017Diesel spray combustion is prone to lead to high soot and nitrogen oxides (NOx) emissions. Regulations impose lowering the emission limits drastically because of the severe impact on health and environment. Apart from health and environmental issues, soot production also results in an efficiency loss due to the heat loss through radiation and late ...

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-

Modeling diesel engine combustion using pressure dependent Flamelet Generated Manifolds
Proceedings of the Combustion Institute, 2011Flamelet Generated Manifolds (FGMs) are constructed and applied to simulations of a conventional compression ignition engine cycle. To study the influence of pressure and temperature variations on the ignition process after the compression stroke, FGMs with several pressure levels are created.

SAE Technical Paper Series, 2010
<div class="section abstract"><div class="htmlview paragraph">A study on the modeling of fuel sprays in diesel engines will be presented. First, modeling of non-reacting diesel spray formation is studied in Fluent and Star-CD. The main objective however is to model combustion of the spray using a generic approach.

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 ...

A numerical study of confined triple flames using a flamelet-generated manifold
Combustion Theory and Modelling, 2004Laminar triple flames are investigated numerically by using detailed and reduced chemical reaction mechanisms. Triple flames are believed to play an essential role in flame propagation in partially premixed systems. In order to reduce the computational cost of the simulations, the flamelet-generated manifold (FGM) method is used to simplify the ...
