The study consisted in the investigation on a prototype of hybrid turbine characterized by a geometry Darrieus with 4 fixed blades and a Savonius, positioned internally at the Darrenius, constituted by flexible wings which vary in their extension, reducing the extension at the increase of…

A final control element is a device that physically changes a process as a result of a change in a control system setpoint. This is typically done with the use of an actuator and a control valve. The actuator accepts a signal from the control…

Lubricants are primarily used to separate two sliding surfaces to minimize friction and wear. They also perform other functions, such as carrying heat and contaminants away from the interface. Lubricants are often liquids, typically consisting of oil and added chemicals, called additives, which help the…

Friction is, by way of definition, the resistance to movement. The significance of this resistance is a feature of the materials, geometries and surface functions of the our bodies in contact, as well as the operating conditions and surroundings. it’s miles regularly proper to reduce…

No one in this world ever has a permanent address. People are always on the move. Some even enjoy that while some find it a stress. It’s no doubt is a stress for new movers. They are not aware of the shifting process and are…
