Aerodynamic optimisation of vertical axis wind turbine blades

This study reports the Computational Fluid Dynamic results of 2D aerofoils and 3D blades with and without pleats for use as Vertical Axis Wind Turbine blades. Investigation of the aerodynamic characteristics of corrugated aerodynamic wings has been the focus of a number of experimental and numerical studies in the past. However, little is still understood of the exact phenomenon causing the increased aerodynamic performance of corrugated aerofoils when compared to their profiled counterparts, although many, often contradicting, theories are presented in literature.

The research has found that corrugations can be used to improve the lift to drag ratios of vertical axis wind turbine blades and therefore their overall performance. The corrugations will also reduce the negative effect of blade soiling and allows for easier manufacture.

A commercially available axial fan is also optimised by reducing operating noise, whilst not reducing performance or energy consumption. 4 paragraphs needed: what was research, how it was research, what were the results, what are the implication of the results.
