Wind tunnel study of wind farms with alternating 2- and 3-bladed wind turbines
With offshore wind farms gaining substantial momentum in recent years, 2-bladed turbines (2BT) are increasingly becoming a viable alternative to 3-bladed counterparts (3BT). In this wind tunnel study, model wind farms with alternating rows of 3BT and 2BT were explored for potential benefits …

Optimization of Wind Turbine Airfoils/Blades and Wind Farm Layouts
… optimization is widely used in the design of wind turbine blades. In this dissertation, a numerical optimization method called Genetic Algorithm (GA) is applied to address the shape optimization of wind turbine airfoils and blades. In recent years, the airfoil sections with blunt trailing edge …

Optimization Of Wind Fence Enclosures For Infrasonic Wind Noise Reduction
A large porous wind barrier enclosure has been built and tested to optimize wind noise reduction at infrasonic frequencies between 0.01-10 Hz in order to develop a technology that is simple, cost effective, and improves upon the limitations of pipe and porous hose arrays. The effects of varying the …

Experimental Investigation of Wind Loading on a Ducted Wind Turbine
Ducted wind turbines (DWT) are designed to operate in the low-speed wind conditions when compared to the conventional horizontal axis wind turbines. The duct/shroud boosts the power output by increasing the mass flow through the turbine. To enhance our understanding on the impacts of turbulence on …

Responses of floating wind turbines to wind and wave excitation
The use of wind power has recently emerged as a promising alternative to conventional electricity generation. However, space requirements and public pressure to place unsightly wind turbines out of visual range make it desirable to move large wind farms offshore and into deeper coastal waters. A …

Modeling wind forcing in phase resolving simulation of nonlinear wind waves
Wind waves in the ocean are a product of complex interaction of turbulent air flow with gravity driven water surface. The coupling is strong and the waves are non-stationary, irregular and highly nonlinear, which restricts the ability of traditional phase averaged models to simulate their complex …

Behavior of Wind Turbine Towers and Blades Under Tornado Wind Fields
The installation rate of wind turbines around the world is increasing significantly. Therefore, wind turbine farms are constructed in plentiful wind resources areas that put a considerable number of wind turbine towers under severe wind conditions. As a result, failures due to unexpected wind loads …
