Journal of Applied Mathematics, Volume 2024, Issue 1, 2024.The streamline upwind Petrov‐Galerkin (SUPG) finite element method was used in this study to investigate the thermal and surface roughness effects on an inclined slider bearing with an unsteady fluid film. One‐dimensional transverse and longitudinal surface roughness models were considered with the supposition that roughness is stochastic and has a ...

International 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 ...

Efficient finite element simulation of full-system elastohydrodynamic lubrication problems [PDF]
, 2012 This thesis is concerned with the efficient numerical solution of problems of elastohydrodynamic lubrication (EHL). Our approach is to consider fully-coupled models in which the governing equations for the lubricating film, the elastic deformation and ...

Thermal Elastohydrodynamic Lubrication Program
, 2021 The program was developed in order to enable investigations of how surface roughness relates to rolling contact fatigue. The goal of the program was only to enable simulations of artificial asperities, indents, and general rough surfaces, not to write a ...
