Published Online: August 5, 2008
...M. A. Kabir; C. Fred Higgs, III; Michael R. Lovell The present investigation analyzes a green, petroleum-free lubricant that is produced by mixing two environmentally benign components—canola oil and boric acid powder. To study the influence of boric acid particle size and solid volume fraction...

...Emmanuel Y. A. Wornyoh; Venkata K. Jasti; C. Fred Higgs, III Research efforts related to dry particulates in sliding contacts are reviewed. In the tribology community, there are primarily two types of dry particulate lubricants that are studied—granular and powder. Granular lubricants usually refer...

... are investigated. The nondimensional load, attitude angle, friction coefficient, and side flow are explored for different eccentricity and diameter-to-width ratios. The numerical results provide an understanding of the performance of powder lubricated journal bearings and are consistent with the experimental...

...C. Fred Higgs,, III; John Tichy Because at extreme temperatures, conventional liquid lubrication breaks down, researchers have proposed using flows of solid particles as a lubricating mechanism. The particles may be powders, which tend to coalesce and slide over one another in sustained contact...

...Manjunath Pappur; M. M. Khonsari This paper presents a systematic development of the theory of powder lubrication with the appropriate formalism based on the fundamentals of fluid mechanics. The theory is capable of predicting flow velocity, fluctuation (pseudo-temperature), powder volume fraction...
