Numerical modelling of combustion has become an important tool for the design of new combustion devices. In order to predict the performance of such machines in terms of fuel efficiency and emissions, detailed chemical models comprising hundreds of chemical components and thousands of chemical reactions, are needed. The complexity of the chemistry makes numerical simulation of combustion a very challenging task. The goal of this research is to develop accurate and efficient combustion models for the investigation of all kind of combustion devices ranging from household applications to gas turbines, furnaces, and engines.
A very efficient method to model flames is the Flamele-Generated Manifold (FGM) method, which has been developed by Van Oijen. This method reduces the computational time of flame simulations by a factor of 100, without loosing (too much) accuracy of the full chemistry model. The FGM method has been developed for premixed laminar flames, but over the years it has been extended to deal with partially-premixed and non-premixed flames as well. It has been successfuly applied in simulations of turbulent flames in DNS, LES, and RANS context. A list of publications on FGM can be found at the website of Jeroen van Oijen.
Currently the FGM method is further developed and applied in a series of research projects:
