 Radial Compressor Design and Optimization

This short course is the regular course on radial compressors thought at VKI to the turbomachinery students specializing in compressors in the context of the “Research Master in Fluid Dynamics”. It provides an overview of the present knowledge and flow models and intends to provide a good background for the people interested in the aerodynamic design of radial compressors. This 5 day course is now made available to a limited number of people from outside VKI. Lectures and exercises are given by Prof. R.A. Van den Braembussche and Prof. T. Verstraete.

The lecture series is foreseen as a regular on-site event. In case the continuously evolving situation does not allow for this,  a fully equivalent virtual meeting will be organized.
