RISEffects of Skew Unidirectional Striated Roughness on Hydrodynamic Lubrication: Part 2—Moving Roughness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The author’s work on the lubrication of unidirectional striated roughness at arbitrary angles to the direction of motion has been extended to the case of moving roughness. The previously derived ...

DDC Lubrication: A New Concept in Tribology
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new lubrication concept is presented, Deep Disconnected Cavities. It differs from the lubrication of microcavities, previously treated by other authors, by the deepness of the cavities. The ...
Finely Striated Lip-Seal Surfaces: Part 1—General Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The work presented previously by To̸nder and Salant (1992) is extended and generalized. In that work it was shown that the fine, axially oriented striations found on some lip-seals, under ...
A Numerical Assessment of the Effect of Striated Roughness on Gas Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based upon the assumption that Reynolds’ equation holds in the presence of roughness, the present work establishes that the film thickness averages previously derived for incompressible lubrication ...
Non-Leaking Lip Seals: A Roughness Effect Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analysis of roughness effects on leakage of lip seals is presented. The generation of fine axially oriented striations has been seen to occur on some lip seals after a certain time of ...
Pressure and Shear Flow in a Rough Hydrodynamic Bearing, Flow Factor Calculation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The lubrication of isotropic rough surfaces has been studied numerically, and the flow factors given in the so-called Average Flow Model have been calculated. Both pressure flow and shear flow ...
Numerical Simulation of the Effects of Three-Dimensional Roughness on Hydrodynamic Lubrication: Correlation Coefficients
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Numerical simulations of the lubrication of rough surfaces have been done using the Finite Element Method. Only pure pressure flow conditions have been considered. The correlation coefficient ...
