Abstract

The objective of this work is to obtain energy from gust produced near the ground surface of a moving object based on the `Boundary layer theory'. According to Boundary layer theory, from the point of contact of the body, there will be a decreasing velocity profile. By placing an Omni-directional wind mill (helix windmill) at an optimum point in this velocity profile, maximum output (electrical energy) is obtained. This highly feasible method is applicable to energy generation using the movement of train or any fast moving objects. This method is highly advantageous because it provides high rotational or mechanical power to the wind blades, which in turn can be converted to electrical power. At places where normal wind mills are installed, the minimum wind speed required is 15km/hr. However, at the places where the gusts are produced by fast moving objects, the minimum wind speed is 25 to 35 km/hr. The proposed method is a better and efficient way to support the government's plans in the promotion of wind energy sector.
