Design Calculation of Vertical Axis Wind Turbine (Savonius Type)
Subject area: Science,Engineering and Technology · Area of research: Mechanical
Abstract
This paper presents the theoretical design of a two-bladed helical Savonius Vertical Axis Wind Turbine (VAWT) for small-scale power generation. Featuring 90? twisted semicircular blades, the design optimizes torque through drag differential and achieves a target output of 1500 Watts. rotor diameter, blade pitch, angle of attack, chord length, shaft strength, and segment spacing?were calculated to optimize the turbine?s aerodynamic performance and ensure reliable power generation. The turbine can operate from wind speeds as low as 2 m/s, making it suitable for Myanmar?s varied wind conditions. The study highlights its potential for decentralized energy use and suggests future improvements through gear and control integration.
