RISAn Application of Pneumatic Phase Shifting to Stabilization of Externally Pressurized Journal Gas Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pneumatic phase shifting is studied as a means for self-excited whirl stabilizations in externally pressurized journal gas-bearings. The pneumatic phase shifting stabilizer is composed of several ...
On the Stabilizing Methods of Externally Pressurized Thrust Gas Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two kinds of stabilizing methods for externally pressurized thrust gas bearings are presented and analyzed. Both stabilizers of them are composed of fluid restriction and capacitance. The first ...
Re-Examination of Film Rupture Boundary Condition in Hydrodynamic Lubrication Under Inertia Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents discussions on the choice and handling of film rupture boundary conditions for the hydrodynamic lubrication under the effect of lubricant inertia forces. Many researchers have ...
Development of Ultrafine Piercing By SiC Fiber Punch
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An integrated micropress was developed for ultrafine piercing of metallic foils by a SiC fiber punch. The fiber punch was produced by a series of processes that use buffing and electrolysis ...
A Theory of an Externally Pressurized Circular Thrust Gas Bearing With Consideration of the Effects of Lubricant Inertia
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A hydrodynamic theory, with consideration of the effects of compressibility and inertia of the lubricant, is applied to externally pressurized gas bearings which consist of circular and parallel ...
A Theoretical Investigation of Pressure Depression in Externally Pressurized Gas-Lubricated Circular Thrust Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical explanation of the experimentally observed depression of the pressure profile in externally pressurized gas-lubricated circular thrust bearings is presented, based on a concept new ...
A Study on Climatological Aspects of Winds in Japan. Part I: Mean Wind Fields and Annual Variations of Winds
Publisher: American Meteorological Society
Abstract: Using the winds in Japan as an example, the validity of the vectorial treatment of the surface wind in climatological investigations has been demonstrated, and the expressions for climatological mean and variability of the ...
A Study on Climatological Aspects of Winds in Japan. Part II: Mean Fields of the Thermal Wind
Publisher: American Meteorological Society
Abstract: Climatelogical aspects of the geostrophic wind calculated from geopotential heights in the planetary boundary layer in Japan have been investigated. The mean geostrophic winds at the 850 mb level nearly agree with the ...
Methods for Estimating the Mean and the Standard Deviation of Wind Direction
Publisher: American Meteorological Society
Abstract: In a recent paid, the author reviewed methods for estimating the mean and the standard deviation of wind direction. Some comments on this subject are now added. If large sporadic eddy fluctuations do not occur in a sampling ...
Spectrum of Long-Period Fluctuations of Surface Wind at Marcus Island
Publisher: American Meteorological Society
Abstract: Spectra of the surface wind at Marcus Island (24°N, 154°E) in the subtropical Pacific area wore constructed over a wide frequency range from 10?1 to 5 ? 10?5 Hz (periods from 6 h to about three years). The major kinetic ...
