    Abstract: One of the important factors that determine the long term efficiency of wind turbine blades is the extent to which the surface finish has been altered from the original state. This can happen either through corrosion or through impingement of particles. This paper aims at analyzing the effect of the later phenomenon on two specific profiles: the NR... Show More

    Abstract: Vertical Axis Wind Turbines development was ignored as compared to horizontal axis wind turbines, due to its inability to generate large power. VAWT's have the advantage of working in turbulent wind and at low height. The power generated by VAWT depends upon the drag and lift forces acting on the blades. This paper is focused on analysis of drag an... Show More
