The VKI Lecture Series on é Combustion in Aero Engines" will take place at the von Karman Institute for Fluid Dynamics (Belgium) in February 1-5, 2010. High pressure two-phase air-kerosene reacting flow, with high levels of turbulence and heat transfer submitted to acoustic waves: this is how the flow in an aero engine combustor could be characterized. In addition, the environmental concerns, which are calling for lower NOx emissions, have become strong technological drivers that need to be taken into account during the design phase. Therefore the lectures will put a particular emphasis on the basic phenomena involved in Low Nox combustor and attempt to establish strong links between fundamental knowledge and design requirements.
