Design and Numerical Modelling of Highway Vertical Axis Wind Turbine

Abstract:

Vertical axis wind turbines (VAWTs) represent a significant advancement in harnessing wind energy, offering enhanced efficiency and adaptability. Their ability to capture wind from any direction makes them particularly suitable for urban environments and areas with unpredictable wind patterns.This study describes the design and its optimization for savonius vertical axis wind turbine for application in efficient energy generation on highways and our objective is to optimize the key parameters of design, including the blade arc angle , overlap ratio, and tip speed ratio to identify the best set of design configuration using Numerical Modelling done with the help of Computational Fluid Dynamics (CFD) Study of Turbine Blade Profile and enhance efficiency indicators like power and torque coefficient to achieve an optimal level of performance. The Outcomes and key findings of this study suggested that a rotor configuration with (Ø = 130°, O_R = 0.15, TSR = 1) demonstrated the highest C_P of 0.473 (47.3% wind to mechanical power conversion) and a C_T of 0.255 (25.5% wind to torque generation), these values suggests an enhanced performance of turbine in terms of capturing wind energy and generating torque, this provides evidence for consideration of these results while defining design criteria for the vertical axis wind turbine suitable to our application.
