INTERNAL COOLING IN TURBOMACHINERY

From May 3 to May 6, 2010

von Karman Institute, Rhode-St-Genèse, Belgium

VKI-LS

The aim of this Lecture Series is to look at the state-of-the-art achievements in internal cooling systems, both from an experimental as from a computational point of view. Although most of the lecturers come from the turbomachinery community, this Lecture Series will also be of interest for those interested in various forced convection heat transfer and cooling problems.

The first lectures will set the industrial background and challenges of the problem. They will be followed by a detailed description of the various experimental approaches available today to quantify the performance of forced convection problems. One lecture will specifically address transient approaches, often preferred for heat transfer measurements. Among the various cooling technique,s impingement is well recognized; it will be addressed in two presentations. The effects of flow rotation on heat transfer will be discussed. Finally a discussion of conjugate heat transfer will be presented.

From the computational point of view, the Lecture Series aims at covering most of the available approaches, ranging from Reynolds Averaged Navier Stokes techniques, Large Eddy and Direct Numerical Simulation approaches and algebraic models for turbulent scalar fluxes with application to heat transfer, internal flows and rotating flows.

The directors of this Lecture Series are Dr Filippo Coletti and Prof. T. Arts, from the von Karman Institute.
