Theoretical analysis of single-layered porous short journal bearing under the lubrication of micropolar fluid

Abstract

The imperative characteristics of micropolar (non-Newtonian) fluid-lubricated short single-layered porous journal bearing are analysed theoretically by an iterative method. With the presence of very few available data for micropolar lubrication, the results acquired in the present study are compared with previously published results using the conventional lubricant and found to be in the perfect covenant. The modified Reynolds equation in case of micropolar fluid is derived and solved numerically to investigate bearing characteristics and to show the comparison with published results in the form of design charts. The results established that the micropolar fluid significantly improves lubricating conditions and load capacity as compared with the corresponding Newtonian case. It has been observed that micropolar fluid-lubricated porous journal bearing gives high load-carrying capacity than other conventional lubricants.
