Large Eddy Simulations of Wind Turbines Employing the Virtual Boundary Method
(2010) In ISRN LUTMDN/TMHP--10/5229--SEDepartment of Energy Sciences
- Abstract
- Large eddy simulations of full geometry wind turbines, employing the virtual
boundary method, have been carried out with the in-house developed CFD-code at
the Division of Fluid Mechanics. The aim is to study the influence of pitch variation
on the wake interaction between two wind turbines, and investigate some of the characteristics
related to the performance and reliability of the CFD-code.
Successful full geometry simulations can avoid the faults introduced by assumptions
made in modelling the blades, thus introducing increased possibilities of investigating
the physical characteristics of wind turbine wakes. Characteristics which are important
in the design process of wind turbines and in the design of wind farms.

The simulations proved to be able to capture the influence of pitch control. Initial
indications of wake meandering have also been shown. There, are however; issues
compromising the results, implying a need of further development within the treatment
of the boundaries of the blades and increased dimensions of the spatial domain. (Less)
