Numerical acoustics, aerodynamic coupling and combustion transients

seven people, limousine, marie curie actions

Training in numerical simulations will be given to predict the onset and amplitude of combustion fluctuations. The numerical methods to be used include computational fluid dynamics (CFD), large-eddy simulations (LES), finite element methods (FEM), finite volume methods (FVM) and lumped parameter approach. Aerodynamic processes in the burner inlet duct (like vortex shedding and fluctuations in fuel-mixture fraction) are important factors. They are caused by the interaction between the acoustic field and the mean flow, and they lead to fluctuations in the rate of combustion and heat release. The fellows will be taught how to predict these processes and their interaction with numerical means. This will be done at the academic partners, where there is expertise in the fundamentals of fluid dynamics, and at the industrial partners, where there is know-how on translating fundamental approaches to technological innovation. Each partner brings in specific advanced knowledge on numerical computation of acoustics, combustion, aerodynamics, numerical code development and design optimization.

Each task represents a topic for a PhD or post-doc project
