Power Law Fluid Model for Thermal Elastohydrodynamic Lubrication
Journal of Advances in Mathematics and Computer Science, 2021 The aim of this paper is to analyse thermal elastohydrodynamic lubrication (TEHL) line contact of rolling a bearing using a non-Newtonian uid that is described by the power law model. The performance characteristics of the rolling bearing are determined for various index for dilatant, Newtonian and pseudo plastic uids.
