A new LLJ model and its application to wind turbine power analysis

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...

Wake Dynamics Study of an H-type Vertical Axis Wind Turbine

Recent developments in wind energy have identified vertical axis wind turbines as a favored candidate for megawatt-scale offshore systems. Compared with the direct horizontal axis competitors they poss higher potentials for scalability and mechanical simplicity. The wake dynamics of an H-type vertical axis wind turbine is investigated using...
