16. Numerical computations of wind turbine wakes
Sammanfattning : Numerical simulations using CFD methods are performed for wind turbine applications. The aim of the project is to get a better understanding of the wake behaviour, which is needed since today’s industrial design codes for wind power applications are based on the BEM (Blade Element Momentum) method.

17. Wind-turbine wake flows - Effects of boundary layers and periodic disturbances
Sammanfattning : The increased fatigue loads and decreased power output of a wind turbine placed in the wake of another turbine is a well-known problem when building new wind-power farms and a subject of intensive research. These problems are caused by the velocity gradients and high turbulence levels present in the wake of a turbine. LÄS MER
18. Locating Wind Power Policy : The Mechanics of Policy Subsystem Interactions
Sammanfattning : This dissertation investigates the drivers behind political decision-making and the policy outcomes resulting from political decisions. It is proposed that in policy processes where political decisions are made at multiple levels or across multiple policy subsystems, policy outcomes can be understood in terms of the mechanisms (i.e. LÄS MER
