| dc.description.abstract | Accurate characterisation of mixing at the subfilter level is a critical aspect in many LES combustion models, such as flamelet based and Conditional Moment Closure models. Several models can be found in the literature, which vary from algebraic relations between resolved magnitudes, to the full transport of the subfilter magnitudes. In this paper a comparative between different published models is made in the context of a amelet based combustion model. A turbulent hydrogen/methane flame is used as test case. |
