New urban vertical axis wind turbine design

Abstract

A different approach for enhancing the performance of a Vertical Axis Wind Turbines (VAWT) for the use in the urban or rural environment and remote isolated residential areas is developed in this study. Recently the small VAWT became more attractive due to the major advantages of this type of turbines in comparison to the horizontal axis wind turbines. By adding a second set of blades (3 x 2=6 blades) that following the rules of biplane airplanes we aim to enhance the overall performance of the VAWT. The model has been made to operate at a maximum power in the range of the TSR between 2 to 2.5. The performances of the VAWT were investigated numerically and experimentally to justify the new proposed design.
