: The rising electricity consumption on highways has led to an increased dependence on fossil fuels for power generation. This not only results in high costs but also contributes to environmental degradation. To address this issue, harnessing renewable energy sources such as wind energy is a viable solution. Wind energy, generated using wind turbines, offers a sustainable and eco-friendly alternative to fossil fuel-based electricity. This study focuses on developing a vertical axis wind turbine (VAWT) that can efficiently generate electricity from the wind produced by moving vehicles on highways. The research aims to evaluate the performance of a VAWT in highway wind speed conditions through a simulation-based approach. The simulation employs the K-omega shear-stress transport (SST) model for turbulence viscosity to analyze the turbine’s aerodynamic behavior. Two primary tests are conducted to determine the most efficient turbine configuration in terms of torque and power output. In Test 1, the turbine’s performance is analyzed by varying the number of blades while keeping the wind speed constant. The goal is to identify the optimal configuration that generates maximum torque and power. The results indicate that a Savonius wind turbine with five blades performs better than models with two, three, and four blades. The five-blade configuration achieves the highest torque and power output, peaking at 140 RPM. Test 2 focuses on optimizing blade radius to enhance efficiency. The selected five-blade turbine is tested with different blade radii to determine the most effective size. The findings reveal that a blade radius of 400 mm delivers superior performance, generating higher torque and power compared to other tested sizes. This suggests that increasing the blade radius within an optimal range improves energy capture and overall efficiency. The study highlights the potential of VAWTs in highway applications, demonstrating that the Savonius turbine with five blades and a 400 mm radius is an effective design for harnessing wind energy from vehicle-induced airflow. Implementing such turbines on highways could contribute to sustainable energy generation, reducing reliance on fossil fuels and promoting environmental conservation. Future research could explore real-world testing and further design optimizations to enhance efficiency and feasibility.
