Blade Element Momentum Theory (BEMT) is the most used method to design horizontal-axis
wind turbines worldwide. This is because BEMT has a low computational cost and easy …

The geometry of a wind turbine must always be optimized in order to capture the maximum
amount of available power. The main geometrical parameters of a wind turbine are chord …

Exergy analysis are carried out on a novel 100 kW wind-to-heat system to investigate the
thermodynamic performances by employing the experimental data. Nine different …

Most small wind turbines do not have pitch adjustment of the blades. This makes starting at
low wind speed a serious challenge which is magnified by the drivetrain resistance caused …

Multi‐bladed windmills usually pump water for agriculture and domestic consumption, often
in remote locations. Although they have been around for over 150 years, their aerodynamic …

This study analyzes actuator disc (AD) models of horizontal-axis turbines to determine
optimal performance, defined as the maximum power extracted at any tip speed ratio. We …

Savonius wind turbines are attractive options due to their simple structure, low noise,
appropriate torque, and independence from the wind direction. In this study, a new …

A Savonius wind turbine is one of the simplest vertical-axis turbines. Several researchers
have been attracted to it because of its simple structure, low noise, appropriate torque, and …

Drivetrain resistance of wind turbines is still challenging, since determining static and
dynamic frictional torque is rather complex. Hence, the main motivation of this work is to …

Aerodynamic performance of a horizontal axis wind turbine blade is affected by its span
stacking whether it is two (2D) or three-dimension (3D). The optimization by including swept …
