RISMagnetohydrodynamic Effects in Composite Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical analysis is made of a composite slider bearing using an electrically conducting lubricant such as a liquid metal in the presence of a magnetic field applied perpendicular to the ...
On the Lubrication of Rough Rollers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Christensen’s stochastic model of hydrodynamic lubrication as extended to two sided roughness is used to study the effect of surface roughness in the analysis of lightly loaded rollers in ...
Lubrication of a Porous Bearing With Surface Corrugations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper considers the surface roughness effects in hydrodynamic porous bearings. On the basis of stochastic theory of hydrodynamic lubrication of rough surfaces developed by Christensen, different ...
Cyclic Squeeze Films in Micropolar Fluid Lubricated Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Reynolds equation for the general case of dynamic loading is derived for fluid suspensions, using the micropolar fluid theory. Detailed consideration is given to the dynamic behavior of ...
Squeeze Film Theory for Micropolar Fluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Needs’ experimental results on thin films deviate considerably from those predicted by the classical theory when the film thickness is less than 0.00127 mm. In recent years there has been a ...
A Microcontinuum Theory for the Elastohydrodynamic Inlet Zone
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The micropolar fluid theory is used to analyze the elastohydrodynamic inlet zone of a line contact. The analysis, which is based on Grubin’s approximation, indicates clearly that the additive ...
Surface Roughness Effects in Infinitely Long Porous Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Christensen’s stochastic theory of hydrodynamic lubrication of rough surfaces is used to study the effect of surface roughness in an infinitely long porous journal bearing operating under steady ...
Roughness Effects in Porous Circular Squeeze-Plates With Arbitrary Wall Thickness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stochastic theory of hydrodynamic lubrication of rough surfaces is used to study the effect of surface roughness on the response of a squeeze film between two circular plates when one ...
Influence of Surface Roughness and Its Orientation on Partial Elastohydrodynamic Lubrication of Rollers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a complete solution for a rough, isothermal elastohydrodynamic line contact operating in the partial lubrication regime is presented. The semianalytical EHD line contact model ...
An Analysis of the Squeeze Film Between Rough Porous Rectangular Plates With Arbitrary Porous Wall Thickness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Christensen’s stochastic theory of hydrodynamic lubrication of rough surfaces is used to study the effects of surface roughness on the response of the squeeze film between rectangular plates ...
