Effect of Diagonal Layout on Efficiency of Twin Vertical Axis Turbine

Article Preview

Abstract:

Vertical axis turbine is one of the tools used to extract tidal current energy. The purpose of this study is to show the effect of diagonal layout on the efficiency of vertical axis tidal turbine (VATT), using commercial software ANSYS CFX. For this purpose the angle between the incoming current flows is varied while the distance between the turbines is kept constant. The layout is observed at an angle of 200, 300, 450, 600 and 900. From study we observed that when the twin turbines are at angle of 900 to the incoming flow, the turbines have maximum efficiency.
