Abstract
Present work deals with the computation of static performance of partial journal bearing, operated with micropolar lubricant. The non-dimensional Reynolds equation governs the lubricant flow in clearance space and finite element method is used to solve it. Static characteristics including bearing load capacity, attitude angle, friction force, friction factor, and side flow are presented. Input parameters are chosen such as partial angles 120° and 180° and a width-diameter ratio (1.0), for a range of micropolar fluid parameters. The numerically simulated results show that the bearing geometry and lubricant micropolar parameters on higher side, provide an improved static performance of partial journal bearing system.
期刊介绍：
The Journal of Engineering Tribology publishes high-quality, peer-reviewed papers from academia and industry worldwide on the engineering science associated with tribology and its applications.
"I am proud to say that I have been part of the tribology research community for almost 20 years. That community has always seemed to me to be highly active, progressive, and closely knit. The conferences are well attended and are characterised by a warmth and friendliness that transcends national boundaries. I see Part J as being an important part of that community, giving us an outlet to publish and promote our scholarly activities. I very much look forward to my term of office as editor of your Journal. I hope you will continue to submit papers, help out with reviewing, and most importantly to read and talk about the work you will find there." Professor Rob Dwyer-Joyce, Sheffield University, UK
