Wind energy is one of the most promising renewable energy resources for power
generation, and rapid growth has been seen in its acceptance since 2000. The most …

Increased concern for environment has led to the search for more environment friendly
sources of energy. Wind energy can be a viable option in this regard. Vertical axis wind …

This paper numerically investigates four methods, namely mesh refinement, General
Richardson Extrapolation (GRE), Grid Convergence Index (GCI), and the fitting method, in …

The dynamic stall phenomenon is characterized by the formation of a leading-edge vortex,
which is responsible for adverse aerodynamic forces and moments adversely impacting the …

Abstract Effects of horizontal oscillations of the freestream velocity superimposed on a pitch
oscillating NACA0012 airfoil were investigated using Computational Fluid Dynamics (CFD) …

Horizontal axis wind turbines (HAWTs) are the mainstream of wind power industry in the
world; however, as turbines are becoming bigger, the maintenance of equipments grows …

The relatively low power coefficient restricts the wide application of vertical axis wind
turbines (VAWTs). An effective solution to this problem is to design specific airfoil profiles …

As the integration of vertical axis wind turbines in the built environment is a promising
alternative to horizontal axis wind turbines, a 2D computational investigation of an …

Abstract The Angle of Attack (AOA) of the Vertical Axis Wind Turbines (VAWTs) blades has a
dominant role in the generation of the aerodynamic forces and the power generation of the …

Flow separation control on oscillating airfoils is crucial for enhancing the efficiency of turbine
blades. In this study, a genetic algorithm was employed to optimize the configuration of a …
