On Mon 13, April, CCRC hosted a
seminar by Dr. Andrea Donini on “Development,
Implementation and Validation of the FGM Technique for Stationary Gas Turbine
Applications”. The seminar, which was held at the Lecture Hall 1, between
Building 5 and building 4, was from 1:00 PM to 2:00 PM.
Dr. Andrea Donini said that to
achieve a precise and efficient modeling of turbulent premixed combustion, the
Flamelet-Generated Manifold (FGM) technique is adopted in his work. The
approach of FGM is based on the idea that the most important aspects of the
internal structure of the flame front should be taken into account. In this
view, a low-dimensional chemical manifold is created on the basis of
one-dimensional flame structures, including nearly all of the transport and
chemical phenomena as observed in three-dimensional flames. In addition, the
progress of the flame is generally described by transport equations for a
limited number of control variables.
He further showed how the
FGM technique is implemented and progressively developed for the inclusion of
all the features that are typically observed in stationary gas-turbine
combustion. These include stratification effects, heat loss and turbulence.
Along this process, the model validity is investigated by comparison with
experimental data or detailed chemistry results.
Donini is a PostDoc researcher at the Combustion Technology group of Eindhoven
University of Technology (Netherlands)
