Abstract:

This article examines how increased wind flow velocity above the ridge of a gable roof influences the torque generated by a Savonius wind turbine. The study consisted of two stages: numerical simulations using SolidWorks Flow Simulation, and quasi-static wind tunnel measurements. The primary aim was to validate a simplified numerical model using experimental data, considering varying geometric parameters: specifically, roof pitch angles (30°, 45°, 60°) and the distance from the turbine's axis to the roof ridge (450–710 mm). A grid sensitivity analysis was performed, and torque values were compared as a function of the rotor's angle of rotation. The observed flow blockage over the ridge resulted in a significant increase in torque, underscoring the importance of strategically positioning the wind turbine where wind speeds are highest. These findings can inform the optimal placement of small VAWT systems in urban settings.
