| Abstract |
Wind turbines are a solution for sustainable energy, significantly reducing carbon emissions and fostering a circular economy for more cost-effective and cleaner power generation, in line with worldwide environmental aspirations. In this context, this research aims to explore a novel two-stage, twisted-blade micro-Vertical-Axis Wind Turbine (mu-VAWT)alternative inspired by the Savonius Rotor (SR). This investigation utilizes the kappa-omega SST turbulence model to explore the power coefficient (CP) and torque coefficient (CT), finding CP values ranging from 0.02 to 0.08 across the turbine by altering the free stream velocity (V). CT analysis further delves into four specific sections, highlighting areas of particular interest. These results are validated by examining velocity contours, pressure contours, and streamlines in four horizontal sections, demonstrating that the proposed turbine model exhibits minimal torque fluctuation. Moreover, the analysis of vertical wind streamlines illustrates very low interference with various wind turbine proposals, underscoring the turbine's efficiency and potential for integration into diverse wind energy projects. |
