Development of a Multiphase Flamelet Generated Manifold for Spray Combustion Simulations

Journal of Engineering for Gas Turbines and Power, 2021
Abstract In this study, a model flame of quasi-one-dimensional (1D) counterflow spray flame has been developed. The two-dimensional (2D) multiphase convection-diffusion-reaction equations have been simplified to one dimension using similarity reduction under the Eulerian framework.

Incorporating unsteady flow-effects in flamelet-generated manifolds

Combustion and Flame, 2008
Detailed simulations are performed for a series of steady and unsteady nonpremixed flames. A specific type of unsteady flamelet simulations are considered, i.e., flamelets subjected to (temporally) varying strain-rates. It is observed that the unsteady flame trajectories move closely along a 2D manifold describing the set of steady diffusion flames in ...

Modelling of Premixed Laminar Flames using Flamelet-Generated Manifolds

Combustion Science and Technology, 2000
In order to reduce the computational cost of flame simulations, several methods have been developed during the last decades, which simplify the description of the reaction kinetics. Most of these methods are based on partial-equilibrium and steady-state assumptions, assuming that most chemical processes have a much smaller time scale than the flow time

Application of Flamelet-Generated Manifolds and Flamelet Analysis of Turbulent Combustion

International Journal for Multiscale Computational Engineering, 2006
Three-dimensional direct numerical simulations are performed of turbulent combustion ofinitially spherical flame kernels. The chemistry is described by a progress variable which isattached to a flamelet library. The merits of this reduction process is studied in detail toassess the validity of the method.

Multidimensional flamelet-generated manifolds for partially premixed combustion

Combustion and Flame, 2010
Flamelet-generated manifolds have been restricted so far to premixed or diffusion flame archetypes, even though the resulting tables have been applied to nonpremixed and partially premixed flame simulations. By using a projection of the full set of mass conservation species balance equations into a restricted subset of the composition space, unsteady ...

Formulation and assessment of flamelet-generated manifolds for reacting interfaces

Combustion and Flame, 2016
The coupling of heat and mass transfer at the surface of solid or liquid fuels is important when modeling near-surface gasification and combustion processes. Modeling the reacting boundary layer with the use of finite-rate chemistry allows for a highly accurate description of the coupling between the flame and fuel surface, but is not tractable when ...
