Abstract The wind turbine blade design is important in obtaining an effective turbine. In the field of energy, it essential to understand and parameters affecting blades order obtain a successful design. However, most are dependent on each other this makes turbines challenging task. This research paper used QBlade software analyze optimize behavior small horizontal axis applies Blade Element Mo...

In this article, the model of a 5 kW small wind turbine blade is developed and improved. Emphasis has been placed on improving blade’s efficiency aerodynamics selecting most optimal material for blade. The QBlade software was used to enhance chord twist. Also, new finite element using ANSYS analyze structure modal problems results presented von Mises stresses deformations three different materi...

Accurate and reproducible aeroelastic load calculations are indispensable for designing modern multi-MW wind turbines. They also essential assessing the reduction capabilities of advanced turbine control strategies. In this paper, we contribute to topic by introducing TUB Controller, an open-source controller capable performing full calculations. It is compatible with software QBlade, which fea...

This study investigates the elastic response characteristics of a floating wind turbine (FOWT) with two vertical-axis turbines (VAWTs), called double-rotor VAWTs. The model consists VAWTs mounted on single semi-submersible structure and employs point mooring, which allows FOWT to always self-align wind. Usually, coupled analysis is used in design FOWTs; however, there no available for In this s...

Much human energy needs are obtained from fossil fuels. This is decreasing day by day. So that the utilization of natural such as solar energy, water and wind being developed. Wind we can find, so it very easy to use using a turbine driving force. The vertical axis type easier apply in places where potential not too large. research was conducted means simulation Qblade v0.963 software comparing...
