11:30 - 13:00 Computational aerodynamics
Turbine technology
Room: Hall G2
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.

Presenter's biography
Biographies are supplied directly by presenters at WindEurope Summit 2016 and are published here uneditedMr. Kimura is a Master course student in The University of Tokyo. He majors in mechanical engineering, and his field of study is Computational Fluid Dynamics (CFD) for wind turbines.
In his resent study, he focus on the wake structure of wind turbine. In particular, he is interested in the relationship between tip vortex and velocity field of wind turbine wake. He plans to go on to Doctor course in order to reveal it by using CFD.
