11:30 - 13:00 Computational aerodynamics
Turbine technology  
          

The session deals with aerodynamics, in particular computational aerodynamics. The session investigates a typical enginering blade element momentum (BEM) aerodynamic model, and demonstrates the merits of less empiric but computationally more comprehensive CFD modelling for yawed conditions and for tip vortex breakdown. We will also discuss the validation by 2D wind tunnel tests for high Reynolds numbers and how to use aerodynamics computations to analyse the effect of protuberances on blades.
