With the increased need for alternative energy sources, wind energy has become a hotly
debated topic. Improving the performance of a wind turbine has been a significant focus of …

Vertical axis wind turbines (VAWTs) have distinctive attributes, for example, exceptional
performance in built environments and high packing density in wind farms. This study …

The present study proposed a novel porous deflector in front of the Savonius wind turbine to
improve the performance. This new deflector was specifically proposed to minimize the …

Wind tunnel tests were conducted to systematically assess the aerodynamic performance of
both H-rotor and helical vertical axis wind turbines (VAWTs) in smooth and turbulent flows …

To enhance the performance of vertical axis wind turbines, a new configuration using twisted
blades in multi-stage Savonius rotors is developed. Accordingly, single-, two-, three-, and …

There is renewed interest in floating vertical axis wind turbines (FVAWTs) as offshore wind
turbines progressively increase in size and move into deeper waters. To explore the …

In this study, a 3D-CFD simulation on the effect of various design and operating parameters,
namely the number of blades, overlap ratio, spacing size, arc angle, shape factor, presence …

A comprehensive three-dimensional numerical analysis is applied in this study to evaluate
the competence of the J-type blades in the vertical axis wind turbines under wide range of …

The energy crisis has forced researchers to look for various non-conventional energy
sources. Wind energy is one of the potential sources, and researchers have invested …

The accelerating global energy crisis and the worsening impacts of climate change have
heightened the demand for alternative energy sources. Wind energy is one of the most …
