Investigating the Effects of Air‐Jet on the Performance of a Hybrid Darrieus–Savonius Wind Turbine

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
The power performance of a hybrid three–bladed H‐Darrieus turbine and a two‐bladed Savonius turbine is analyzed by adding air‐jet deflectors. Aluminum is selected for the blade design due to its high strength, lightweight, and corrosion resistance. Experimental analyses were conducted using the developed prototype with and without an air jet in an open

Optimizing a Straight‐Bladed Vertical Axis Wind Turbine With Computational Fluid Dynamics (CFD), Artificial Neural Network (ANN), and Genetic Algorithm (GA)

Energy Science &Engineering, Volume 13, Issue 12, Page 6003-6016, December 2025.
ABSTRACT Vertical axis wind turbine (VAWT) is a suitable renewable power generation tool for use in urban areas, especially at low wind speeds and with low noise level. However, an approach with accurate results, acceptable time consumption, and cost for optimizing this turbine is not reported in the literature.
