Bearing Performance Analysis of the Thermal and Surface Roughness Effects by Finite Element Method on Slider Bearings Through Non‐Newtonian Fluid‐Type Lubricant

open access: yesInternational Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.
The finite element method was used in this study to explore the impact of surface roughness and thermal characteristics on slider bearings with non‐Newtonian power‐law fluid flow lubricant. One‐dimensional transverse and longitudinal surface roughness models were considered under the stochastic assumption that roughness has a Gaussian random ...
