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
