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.  

Andrea Donini is a PostDoc researcher at the Combustion Technology group of Eindhoven University of Technology (Netherlands)
