1. Ride The Wind : Symbiotic Business Model Innovation for the Chinese Wind Power Industry
Sammanfattning : China has become one of the world’s leading countries in renewable energy, particularly in wind power. Goldwind Science and Technology has become not only the largest wind turbine manufacturer in China, but also one of the largest in the world. LÄS MER
2. Fluid Mechanics of Vertical Axis Turbines : Simulations and Model Development
Sammanfattning : Two computationally fast fluid mechanical models for vertical axis turbines are the streamtube and the vortex model. The streamtube model is the fastest, allowing three-dimensional modeling of the turbine, but lacks a proper time-dependent description of the flow through the turbine. LÄS MER
3. Wind Power and Natural Disasters
Sammanfattning : Wind power can be related to natural disasters in several ways. This licentiate thesis gives some background and introduces four papers devoted to two aspects of this relation. The first section looks into how small-scale wind energy converters (WECs) could be used to generate power after a natural disaster. LÄS MER
4. Numerical Computations of Wakes Behind Wind Farms
Sammanfattning : More and larger wind farms are planned offshore. As the most suitable build sites are limited wind farms will be constructed near to each other in so called wind farm clusters. Behind the wind turbines in these farms there is a disrupted flow of air called a wake that is characterized by reduced wind speed and increased turbulence. LÄS MER
5. Numerical Computations of Wakes Behind Wind Farms : A tool to study Farm to Farm interaction
Sammanfattning : More and larger wind farms are planned offshore. As the most suitable sites to build are limited these new wind farms will be constructed near to each other in so called wind farm clusters. Behind the wind turbines in these farms there is a disrupted flow of air called a wake that is characterized by reduced wind speed and increased turbulence. LÄS MER
