1. Numerical computations of wind turbine wakes and wake interaction : Optimization and control
Abstract : In the present thesis the wake flow behind wind turbines is analyzed numerically using large-eddy simulations. The wind turbine rotors are modeled by using either the actuator disc method or the actuator line method in which the blades are represented by body forces computed with airfoil data. READ MORE

2. Wind-turbine wake flows - Effects of boundary layers and periodic disturbances
Abstract : 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. READ MORE

5. Aerodynamic Design and Installation Effects of Automotive Electric Cooling Fans
Abstract : Electric cooling fans play a crucial role in automotive thermal management. They generate the airflow required for heat rejection from the expended coolant circulating within the heat exchanger. This thesis focuses on the aerodynamic design and installation effects of electric cooling fans or "E-fans". READ MORE
