TLDR
In this paper, the behavior of smart lubricants is described by Bingham model of non-Newtonian fluid flow, which provides better dynamic behavior than conventional lubricants and hence is more suitable for the application of fluid film bearings.Abstract:
Lubrication of fluid film bearings with smart lubricants provides better dynamic behavior. The behavior of these smart lubricants is described by Bingham model of non-Newtonian fluid flow. In the r...read more

A comparative performance assessment of a hydrodynamic journal bearing lubricated with oil and magnetorheological fluid
TL;DR: In this article, the results of a journal bearing with magnetorheological fluid activated by a local constant magnetic field to vary both the local flow resistance and pressure were investigated. But the results were not compared with the same geometrical bearing lubricated with oil.

Rheological texture in a journal bearing with magnetorheological fluids
TL;DR: In this paper, a new type of hybrid journal bearing was proposed in which a magnetorheological fluid is used in combination with local magnetic fields, such that the hydrodynamic and hydrostatic working regimes are not compromised.
Journal ArticleDOI
Experimental results on a hydrostatic bearing lubricated with a magnetorheological fluid
TL;DR: In this paper, the magnetic field is applied only locally at the outer edges of the bearing with the use of an electromagnet, and the principle is demonstrated with an experimental setup and a model from literature.

Effect of the ER lubricant behaviour on the performance of spherical recessed hydrostatic thrust bearing
Nitin Agrawal,Satish C. Sharma +1 more
TL;DR: In this paper, a spherical thrust bearing system with a capillary restrictor lubricated with electro-rheological (ER) lubricant has been described, and the influence of axial eccentricity ratio and various value of imposed electric field on bearing performance has been investigated.

Lubrication theory for Bingham plastics
TL;DR: In this paper, an exact thin film simulation for a Bingham plastic fluid is presented, which requires no additional approximations to those used in the derivation of the general Reynolds equation, and requires no numerical regularization of the BPL fluid model and can still be used on any lubricating film geometry.

A Laser Surface Textured Parallel Thrust Bearing
TL;DR: In this article, the potential use of a new technology of laser surface texturing (LST) in parallel thrust bearings is theoretically investigated, where the surface texture has the form of micro-dimples with pre-selected diameter, depth, and area density.

Experimental Investigation of Laser Surface Textured Parallel Thrust Bearings
TL;DR: In this article, the performance of unidirectional and bi-directional partial-LST bearing with a baseline, untextured bearing is compared with that of a baseline bearing in terms of increased clearance and reduced friction.

Effect of textured area on the performances of a hydrodynamic journal bearing
TL;DR: In this article, a numerical model is used to analyze the cylindrical texture shape effect on the characteristics of a hydrodynamic journal bearing and the theoretical results show that the most important characteristics can be improved through an appropriate arrangement of the textured area on the contact surface.
