A dictionary random choice method for turbulent combustion

The Pdf Method for Turbulent Combustion

PDF methods provide a means of calculating the properties of turbulent reacting flobs. They have been successfully applied to many turbulent flames, including some with finite-rate kinetic effects. Here the methods are reviewed with an emphasis on computational issues and on their application to turbulent combustion.

Application of a Flame Dictionary Method in Turbulent Premixed Flame Modeling. Construction of a Flame Dictionary

|The construction of a ame dictionary of ame speeds and preheat thicknesses for a given reaction will be discussed. Once the entries of the dictionary have been established, they can be accessed by researchers and programmers to be used in diierent combustion applications. An application of the ame dictionary for turbulent combustion in a circular cylinder is given. Chemical reactions are often...

A Clustering Method for Identifying Regions of Interest in Turbulent Combustion Tensor Fields

Flamelet Analysis of Turbulent Combustion

Three-dimensional direct numerical simulations are performed of turbulent combustion of initially spherical flame kernels. The chemistry is described by a progress variable which is attached to a flamelet library. The influence of flame stretch and curvature on the local mass burning rate is studied and compared to an analytical model. It is found that there is a good agreement between the simu...

A generalised multiple mapping conditioning approach for turbulent combustion

This paper follows the evolution in understanding of the multiple mapping monditioning (MMC) approach for turbulent combustion and reviews different implementations of MMC models. As the MMC name suggests, the original version represents a consistent combination of CMC-type conditional equations (conditional moment closure) and generalised mapping closure. It seems that the strength of the MMC ...
