_{Research Interests}

• Simulation of turbulent combustion
• Large eddy simulation/filtered density function methods (LES/FDF)
• Simulation of coal combustion with LES
• Multidimensional flamelet modeling
• Multiphase flows

_Project

Martin will work on the DFG project „Mehrdimensionale Flamelet-Modellierung für die LES von Kohlestaubflammen“ which will be conducted in collaboration with the universities in Stuttgart and Freiberg. The focus of his work will be the implementation of a multidimensional flamelet model for coal combustion into the in-house PsiPhi LES code. This model promises a better predictability of pulverized coal flame LES.
