Globally, wind energy is one of the most advanced sustainable power generation technologies, offering an environmentally friendly and cost-effective solution to meet the increasing demand for clean Energy. A critical factor in the successful conversion of wind energy is the utilization of wind turbine technology, and researchers continuously seek innovative designs to optimize wind turbines’ performance. Among the modern technologies developed for wind energy generation, Archimedes Screw Wind Turbine (AScWT) stands out as an advanced horizontal-axis turbine specifically designed for residential applications. This unique design aims to enhance energy collection while maintaining efficiency in lower wind conditions. The numerical analysis was carried out using Computational Fluid Dynamics (CFD) in ANSYS Fluent, employing the SST k–ω turbulence model under steady-state conditions to simulate the turbine’s performance. Through comprehensive parametric studies, the current research aimed to identify the optimal dimensions required to achieve maximum power coefficient (CP max). The study examined critical design variables, particularly the ratio between the inner and outer diameters (d/D), length (L), pitch (P), and inclination angle (α), to determine their impact on the turbine’s performance. The results revealed that (d/D) and (α) have the most significant influence on CP, whereas L and P had relatively minor effects. One of the key findings was that reducing the (d/D) ratio could significantly increase the collected power by 209.8% at an inclination angle of 50º, and a wind speed of 2 m/s. Moreover, the best AScWT dimensions improved CPmax by approximately 100.08% compared to the original design. These findings underscore the substantial potential of the AScWT design in improving wind energy efficiency, particularly for residential applications, rendering it a promising alternative for sustainable energy production in both urban and rural settings.
