Investigate the Potential of Vehicle-Induced Turbulence for Power Generation Using Vertical Axis Wind Turbines

The increasing energy demand for urban infrastructure, particularly street lighting, has led to a search for alternative renewable energy sources. One promising approach is harnessing vehicle-induced turbulence (VIT) to generate power using vertical axis wind turbines (VAWTs). Conventional street lighting relies heavily on fossil fuels, contributing to high operational costs and environmental concerns. Additionally, urban areas with high vehicle traffic produce significant yet untapped airflow energy, which, if efficiently captured, could supplement power generation. This study aims to assess the feasibility of utilizing VIT for power generation through optimized VAWT design. Computational fluid dynamics (CFD) simulations using ANSYS software are employed to analyze airflow patterns and the aerodynamic performance of the turbine. Field data on VIT characteristics and road traffic density are also collected to determine optimal turbine placement and airflow best angle. Preliminary findings indicate that airflow velocity and its best angle (120 degree) near roads can generate sufficient mechanical energy to drive small-scale VAWTs, making them a potential source of renewable energy. Integrating these turbines into urban infrastructure such as street lighting poles, highway medians, and roadside structures could reduce electricity costs, minimize carbon emissions, and enhance lighting reliability in adverse weather conditions. This research provides insights into the potential of VIT as a sustainable energy source, contributing to cleaner and more energy-efficient urban environments.
