Study the Foundation Effect on the Hydrodynamic Bearing Performance. [PDF]
The hydrodynamic bearings are important components of most of the rotary parts in different applications. The current study examines the performance of the traditional type, which is the most common because they are easy to the manufactured, relatively ...

An Experimental Investigation of Hydrodynamic Journal Bearing with Different Oil Grades [PDF]
Journal bearings are known to be intrinsic components in different marine applications. They are regarded as the most instrumental means by which large loads could be transmitted at mean speed of rotation.

Analysis for Hydrodynamic Wedge-Platform Thrust Slider Bearing with Ultralow Surface Separation
For the case of ultralow surface separation, in a hydrodynamic wedge-platform thrust slider bearing, the outlet zone and a portion of the inlet zone are in boundary lubrication, while most of the inlet zone is in the multiscale lubrication contributed by

Multiscale Analysis of Hydrodynamic Step Bearing with Ultra Low Surface Separations [PDF]
The paper presents the multiscale analysis for the hydrodynamic step bearing with ultra low surface clearances where only the physical adsorbed layer is present in the outlet zone and the continuum fluid flow mainly occurs in the inlet zone. This bearing

A New THL Model for High Accuracy of Predicted Journal Surface Temperature
A thermo-hydrodynamic lubrication (THL) theory is applied to journal bearings that support large-sized high-speed rotary machineries and it is confirmed that the maximum pad surface temperature under operation is below an allowable limit value.
