6. Studies of a Vertical Axis Turbine for Marine Current Energy Conversion : Electrical system and turbine performance
Sammanfattning : Ocean energy is a field of growing interest when it comes to renewable energy thanks to its high density of energy per unit area, and to the high predictability. Conversion of hydrokinetic energy, found in marine currents, is the utilization of the energy in free-flowing water for conversion to electric energy. LÄS MER
7. Aeroacoustic Prediction for Vertical Axis Wind Turbines
Sammanfattning : This thesis investigates the aerodynamic and aeroacoustic prediction of vertical axis wind turbines, using computational fluid dynamics simulations. Noise pollution from wind turbines is one of the disadvantages of wind energy, calling for strategies to reduce noise levels. LÄS MER
8. Analytical Aerodynamic Simulation Tools for Vertical Axis Wind Turbines
Sammanfattning : Wind power is a renewable energy source that is today the fastest growing solution to reduce CO2 emissions in the electric energy mix. Upwind horizontal axis wind turbine with three blades has been the preferred technical choice for more than two decades. This horizontal axis concept is today widely leading the market. LÄS MER
9. Direct Driven Generators for Vertical Axis Wind Turbines
Sammanfattning : Wind power is a renewable energy source that is increasingly used all over the world. Most wind turbines have a horizontal axis of rotation but a few have a vertical axis of rotation. The concept presented in this thesis is a straight-bladed vertical axis wind turbine with a direct driven cable-wound permanent magnet synchronous generator. LÄS MER
10. Electromechanics of Vertical Axis Wind Turbines
Sammanfattning : Wind power is an established mean of clean energy production and the modern horizontal axis wind turbine has become a common sight. The need for maintenance is high and future wind turbines may need to be improved to enable more remote and offshore locations. LÄS MER
