Selecting a suitable oil

The velocity of the oil jet should be sufficiently high (≥ 15 m/s) to penetrate the turbulence surrounding the rotating bearing Oil jet lubrication is used for very high speed operation where a sufficient but not excessive amount of oil should be supplied to the bearing without increasing the operating temperature

Simulation of the Motion of Spherical Fuel Pellets in the

Two computational models – potential flow and quasinewtonian viscous liquid – are developed for describing a motion of spherical fuel pellets in the core of a high-temperature gas-cooled reactor Two types of boundary conditions are obtained They take account of the slipping of the fuel pellets on the vertical and inclined walls of the core and the coefficient of internal friction

Proof of the elusive high

CuO is the only known binary multiferroic compound and due to its high transition temperature into the multiferroic state it has been extensively studied In comparison to other prototype multiferroics the nature and even the existence of the high-temperature incommensurate paraelectric phase (AF3) were strongly debated—both experimentally and theoretically—since it is stable for only a

Spherical tokamak

A spherical tokamak is a type of fusion power device based on the tokamak principle It is notable for its very narrow profile or aspect ratio A traditional tokamak has a toroidal confinement area that gives it an overall shape similar to a donut complete with a large hole in the middle The spherical tokamak reduces the size of the hole as much as possible resulting in a plasma shape that
