Fred's research revolves around the development and
application of advanced computational modelling techniques
to engineering based research problems.
Current activities relate to the development of a
methodology for modelling turbulent combustion based
on Large-Eddy Simulation (LES) of turbulent flow,
the Stochastic Fields method for the treatment of
turbulence-chemistry interaction and a Lagrangian
formulation for fuel droplets. The Stochastic Fields method
solves the modelled evolution equation for the filtered
fine grained Probability Density Function, coupled
with advanced descriptions of the chemical reactions taking
place during combustion the description of the
complex interactions between
turbulence and chemical processes is possible. This
approach allows a wide range of combusting processes
to be investigated and have included flame extinction
and relight, premixed and partially premixed combustion
with gaseous and liquid fuels.
This work has led to research supported by Rolls-Royce
(UK and Germany) and Siemens Industrial Turbomachinery
and involvement in EU funded research consortia.
