Analysis of Flow Models for Aerostatic Thrust Bearings with Porous Material The models are based on the coupling of the Reynolds equation for lubricants (REL) and the determination of pressure drop through porous material by Darcy... A Schimpf,Y Gu - 《机械工程与自动化:英文版》 被引量: 0发...
The effect of couple stress fluids on the static and dynamic characteristics of squeeze film lubrication in finite porous journal bearings is theoretically studied on the basis of Stokes [16] constitutive equations for couple stress fluid. The film pressure distribution is solved numerically by using ...

The treatment of Reynolds equation when the film thickness is unknown and the center of pressure is known, together with the energy and the bending equation, allows a realistic simulation of the performance of large thrust bearing. In a spring-supported thrust-pad bearing the distortion caused by...
P. E. Clapeyron (1834) between the physical quantities defining the state of an ideal gas: the gas pressure p, the volume of the gas V, and the absolute temperature T. The Clapeyron equation is written in the form pV = BT, where the proportionality coefficient B depends on the mass of...

(b) Sails use the same technique to generate part of their thrust. Thus pressure P2 over the second opening is reduced by 12ρv2212ρv22, and so the fluid in the manometer rises by h on the side connected to the second opening, where h∝12ρv22h∝12ρv22 (Recall that the symbol ...
A stable and 40Ar/39Ar isotope study of a major thrust in the Helvetic nappes (Swiss Alps): Evidence for fluid flow and constraints on nappe kinematics Stable isotope and 40Ar/39Ar measurements were made on samples associated with a major tectonic discontinuity in the Helvetic Alps, t... Anne...
The pressure profile obtained when the pad is in equilibrium is used to analyze the distortion of the spring-supported thrust pad. Such a type of analysis is necessary to predict the actual performance of a thrust pad bearing, since the thrust pad is not likely to operate with the initially...
