Straight-bladed vertical axis wind turbines (SB-VAWTs) are increasingly recognized as a
favorable choice for wind energy systems in both urban and offshore environments. This …

This study proposes a novel vertical axis wind turbine (VAWT) design with flexible blades
aiming to improve their energy extraction capability. The blade deformation is achieved …

Abstract Vertical Axis Wind Turbines (VAWTs) have attracted considerable attention in
recent years due to their potential for harvesting wind energy in urban areas and low wind …

Abstract The Double Darrieus Vertical Axis Wind Turbine (DD-VAWT) effectively enhances
wind energy efficiency at low tip speed ratios. In this study, the multi-objective optimization …

This study assesses the impact of three morphed trailing-edge flap (MTEF) parameters (flap
deflection angle β, flap length b, and flap span length l) on increasing power and axial thrust …

In this research, the computational fluid dynamics (CFD) approaches using ANSYS Fluent
solver was employed to evaluate new designs of the delta-shaped bladed Darrieus …

In this study, the aerodynamic performance of a cambered wind turbine airfoil with a partially
flexible membrane material on its suction surface was examined experimentally across …

Stall occurs in an airfoil when it reaches a critical angle of attack and the flow detaches from
its surface, causes a sudden reduction in lift coefficient values. Several mechanisms have …

Improving turbine performance has become increasingly crucial in recent decades. Two
main approaches are used to increase turbine efficiency. The first approach involves …
