mixing in turbulent flames:
ve and model
development using direct numerical s
Summary of objectives:
of fuel and air at scales relevant for combustion i
s commonly called micro
The current mathematical models describing
mixing phenomena in
turbulent flame calculations are based on our understanding of simplified situations, such
of passive scalars
in the absence of combustion.
ic studies show the significant influence
of heat release and density fluctuations
on the mixing process.
In this project we seek to address the shortcomings of models for m
ixing in turbulent
combustion by conducting direct numerical simulations (DNS).
Three dimensional DNS
with complex chemistry allows detailed evaluation of models.
The deep knowledge thus
gained will be translated into a mathematical model which can be easi
ly incorporated into
industrial CFD codes.
The expected outcome of this project is valida
ted models which are
based on the fundamental conservation equation
