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), so named because of their vertical axis of rotation, are
a sustainable, opportune, and versatile means of producing energy. Their operation is not …

The winglet has been widely deployed in the optimization of the blade design as it reduces
the tip loss of the blade and increases the swept area of the rotor. However, previous studies …

The combination of Savonius and Darrieus turbines had been proposed with the aim to
overcome the weaknesses and complement the strengths from each design. This paper …

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 …

The present study conducted a 2-dimensional numerical simulation using the Computational
Fluid Dynamics (CFD) method for a Darrieus Vertical Axis Wind Turbine (VAWT). This study …

The Φ-shaped Darrieus wind turbines offer promising applications owing to their
omnidirectionality and structural advantages. However, their poor performance at low tip …

The present study aims to optimize the design of a vertical axis wind turbine (VAWT) and
analyze how the design factors affect the power coefficient of VAWT. The considered factors …

This study aims to develop a comprehensive evaluation approach to analyze and grade the
energy sources based on statistical data. A brief bibliometric analysis for energy sources …

The demand for alternative and renewable energy sources has been substantially growing
in recent years, mainly steered by economic and environmental inconveniences of …
