Friction and Windage Losses in Pelton Wheels

2016
Friction and windage losses in Pelton wheels arise because the air around the Pelton wheel is continuously entrained to circulate and the rotation of Pelton wheels is persistently resisted by air friction on the wheel surface. These effects are therefore referred to as , and in practical applications, these two types of losses depend on designs of the ...

SOURCES OF WINDAGE POWER LOSS IN SALIENT POLES HYDROGENERATOR

2017
Due to the fact that hydro-generators are primarily electrical machines, traditionally insufficient attention is paid to aerodynamics within the machine. Consequently, the existing analytical methods for windage loss calculations, which in the hydro-generator can participate with more than 30% of total losses, are quite simplified and are based largely

Windage Characteristics of a Compressor Stator Well Cavity

Volume 8: Heat Transfer: Internal Air Systems; Heat Transfer: Internal Cooling; Industrial and Cogeneration
Abstract This article aims at the investigation of a generic compressor stator well cavity flowfield of a high pressure compressor stage. Swirl ratio, static pressure distributions are thoroughly investigated together with windage power for three different engine thrust levels and three different clearance levels at high thrust cases. An

Windage and Axial Friction Losses of High Speed Generator

2003 International Joint Power Generation Conference, 2003
Air-cooled generators have been fulfilling a wide range of applications recently. Concurrent with a low cost target, the market demands high efficiency and high performance designs. Windage and friction losses, caused by rotor rotation and cooling gas flowing through the ventilation circuits, represents one of the largest loss components in air-cooled ...
