Design of Domestic Helix Vertical Axis Wind Turbine to Extract Energy from Exhaust Fans

The application of wind energy in power generation is increasing day by day. Horizontal axis wind turbines (HAWT) are considered more efficient than vertical axis wind turbines (VAWT) but with urbanization and limited access to wind in cities, VAWT may offer greater advantages, as HAWT are generally used in wind farms as large wind turbines. In many high altitude regions, average wind velocity is around 5-8ms -1 which can be utilized for electricity production, but in cities, that are at lower altitudes and are congested, the kinetic energy of exhaust fans can be used for electricity production. This paper describes the design of VAWT that can be used to generate electricity at domestic level using the energy from exhaust fans.
