Abstract
This research investigates the design optimization of a small-scale Vertical Axis Wind Turbine (VAWT) utilizing helical rotor blades fabricated from graphene-reinforced polyethylene terephthalate. While previous studies have largely concentrated on largescale turbines for rural environments or on high-performance composite materials that often compromise recyclability, this research addresses the specific challenges associated with small-scale VAWTs intended for urban and populated areas. The study identified tip speed ratio, helical angle, and blade length as critical design parameters. Optimization of these parameters was achieved through systematic evaluation of their impact on the turbine’s aerodynamic performance, quantified by the coefficient of performance. Structural and aerodynamic load analyses were performed across multiple configurations, highlighting a helical twist angle of 60° combined with a NACA0018 airfoil, a rotor radius of 0.4 meters, and a blade length of 1.5 meters as optimal. Additionally, the optimized design demonstrated peak performance at an operational range of 100-120 RPM, underscoring the turbine’s effectiveness and structural integrity for urban energy generation applications.
