Among renewable sources of energy, wind is the most widely used resource due to its
commercial acceptance, low cost and ease of operation and maintenance, relatively much …

The development and utilization of clean energy is becoming more extensive, and wind
power generation is one of the key points of this. Occasionally, wind turbines are faced with …

Wind turbines can be controlled by controlling the generator speed and adjusting the blade
angle and the total rotation of a turbine. Wind energy is one of the main types of renewable …

This paper studies the interactions of rotation and end effects and its effect on the flow
around a rapidly rotating circular cylinder with two flat ends, using the large eddy simulation …

Wind energy is a clean and renewable source of energy. This study seeks to explore the
potential for utilising wind power for merchant ships. A new type of Flettner rotor (rotating …

The purpose of this study is to explore the potentiality of wind propulsion on semi-
submersible ships. A new type of Flettner rotor (two rotating cylinders) system installed on a …

Material and mechanical properties of NiTi shape memory alloys strongly depend on the
fabrication process parameters and the resulting microstructure. In selective laser melting …

The lift to drag ratio is the most determining factor in power efficiency of wind conversion
systems such as wind turbines. The lift to drag ratio can be enhanced considerably using …

In the power system, frequency stability is critical. The wind turbine oscillates (depending on
the wind speed) and is of low inertia. Thus, wind turbines face the issue of power system …

Reduced drag, increased lift and, consequently, increased vital ratio and lift-to-drag
coefficients are crucial in almost all efficient micro air vehicles. Riblet geometries use a …
