ADVANCES IN AERO-ACOUSTICS AND THERMO-ACOUSTICS
From November 15 to 19, 2010
von Karman Institute, Rhode-St-Genèse, Belgium
The accurate modelling of the stability properties of energy transport and conversion processes, such as pipelines, gas turbines, industrial heaters or domestic heating systems, is facing aero-acoustical and thermo-acoustical issues hindering their economic sustainability. The aim of this EU sponsored course (Marie-Curie Research Training Network AETHER) is to present the state-of-the-art review in this multi-disciplinary engineering field of aero- and thermo-acoustical coupling in energy conversion processes, in a form accessible to both researchers and industrial engineers. After providing the theory of stability analysis, the emphasis will be put on the modeling of combustion and unsteady flow, including the interaction of both of them with acoustics. Biomass combustion, experimental methods in thermo-acoustics, non-linearities and non-normality effects will also be covered as well as passive and active control of aero- and thermo-acoustical systems.
The Director of this lecture series is Professor C. Schram of the von Karman Institute for Fluid Dynamics.
Fellowship
