    Unconventional Energy Harvesting From Wind Velocity And Viv Resonance Phenomenon By Using Bladeless Wind Turbine (Blwt)
    (Department of Electrical and Electronic Engineering, 2020-12) ZILANI, MD. ABDUL KADER; HOSSEN, AKTER
    Electric power is mostly produced by using conventional fuel, which gradually increases the atmospheric temperature and pollutes the environment. That is why the majority of countries are aware of the destructive effect of using conventional fuel and corroborates their plan for achieving electric power from renewable energy source. Electrical Power generation from wind is now growing renewable energy harvesting source using wind turbine because of its higher efficiency. This thesis proposed a wind power production system on the coastal side by using vortex induced vibration of Bladeless wind turbine. In this turbine, when wind passes outside the circular mast, it creates a vortex-induced vibration in its body due to mast vortices. This displacement of the mast rotates a pulley with the help of a crankshaft. Then the rotation of the pulley rotates a dc generator to produce electricity. A prototype of the proposed turbine was designed to record the corresponding output. It has been observed that 2.93V and 2.38A were obtained for 4.1ms-1 wind velocity and 7.56V, 5.39A were obtained for 6.5ms-1 wind velocity across a variable resistive load. A comparison was also done comparing the existing output with the proposed one for measuring the efficiency. For the proposed model of BLWT, the maximum efficiency was obtained to be around 46%.
