Kemp, R. (author)
This thesis addresses the process of airfoil optimization for vertical axis wind turbines (VAWT). The airfoils are designed for large scale turbines above 5 MW. The VAWT concept is relevant for offshore floating wind energy, because of its low center of gravity (stability) and their simplicity (low maintenance). An optimal tip speed ratio of 4-4...

Since the beginning of the century the field of airborne wind energy has emerged to provide with new means of generating renewable energy. It's ability to access higher altitudes and it's relatively low material requirements with respect to conventional wind turbines, have inspired several research institutes and commercial parties to invest...

Energy demand from wind greatly increases, as such more remote sites need to be explored in order to find good wind resources. These remote sites are driving the industry further offshore and therefore into extreme wind and sea conditions. This push towards extreme conditions requires technological advancements concerning the wind turbine loads,...

The wake geometry of a Vertical Axis Wind Turbine (VAWT) is unlike the standard Horizontal Axis Wind Turbine (HAWT). The blades of the turbine continuously passes through its own wake, creating complex wake-body interactions such as flow separation and dynamic stall, and convectional grid-based numerical method which is capable of describing...

It is the objective of this graduation research to determine the nations with the highest deployment opportunity for airborne wind energy (AWE) generation systems. Compared to conventional, ground based, wind energy systems, the flying structure of the airborne wind turbine substitutes the rotor blades and a tether substitutes the tower. These...

As the world demands cleaner, sustainable and economical energy sources, the wind energy academia and industry battles to increase performance and reduce costs. One of the promising fields of study is wind turbine wakes in wind farms. The position of the turbines within the layout affects the intensity of their wake effects, such as reduced wind...

In an effort to achieve economic sustainability, the major challenge for offshore wind remains to bring down costs by approximately 35 % before 2020. With wind farm sites going into deeper waters, further from shore, with more difficult bottom conditions and rougher wave climate, costs are rising faster than the improvements in the technology...

A large number of wind energy installations exist on rich wind resource sites. Nevertheless, estimates show that about 50% of the world’s wind energy resource has a wind speed of 7 m/s or less. For these low wind speed resource areas, low wind turbine technology is required. For this reason, this DTU Wind Energy master project, in cooperation...

The world’s energy consumption is rising, which will eventually result in the depletion of fossil fuels. A transition from fossil fuels to renewable energy sources as main energy supply has to be achieved to ensure the world’s energy supply on the long term [9]. To ensure the world’s energy supply, the European Commission adopted the climate and...

Low level jets (LLJs) are situations where wind speed maximums occurs close to the surface. Unfortunately, the influence of LLJs on wind turbine power production is still difficult and costly to quantify due to that the existing LLJ models are all time-based. The work that is done in this report addresses the research question should low level...

Given the prime importance of wind tunnel setup when it comes to aero-elastic study, the main intent of this project is to devise a mechanism for supporting system of 2D aero-elasticity experiment in the Red Wind Tunnel Facility at DTU that allows three-degree-of-freedom motion of the rigid model. This project work is mainly inspired by the fact...

Wind turbine noise has become an important issue when developing onshore<br/>wind farms as turbines have scale up rapidly in the latest decades. The interest of this project is focused on the characterization and modelling of noise as a source based on the specific physics from wind turbines. A dedicated evaluation of wind turbine noise...
