Finite element analysis of a journal bearing lubricated with nano lubricants

Abstract

The oil-film pressure is a key factor used to examine the performance of a journal bearing. The developed nano lubricant was used as an alternate lubricant for journal bearing system described in the present study. For this purpose, oil-film pressure of the journal bearing was analyzed by using COMSOL multi physics and developed the oil-film pressure of the journal bearing lubricated with various lubricants. The COMSOL results stated that, this model is suitable for analyzing the pressure of an oil-film of the journal bearing and these results were compared with experimental results.
