Non-Newtonian Effects of Rabinowitsch Fluid on the Performance of Inclined Stepped Composite Bearings

The theoretical analysis of rheological effects of Rabinowitsch fluid on the steady and dynamic characteristics of inclined stepped composite bearings is investigated. The Rabinowitsch fluid model is considered to account the pseudoplastic and dilatant nature of the lubricant due to the presence of...
