Résumé :

A progressive interest is granted to the textured surfaces in a journal bearing. The use of surfaces with certain shapes and dispositions of textures can be an effective approachto improve the performance of hydrodynamic bearings. This paper presents thenumerical approach used to analyze the effect of cylindrical texture form on thecharacteristics of a hydrodynamic contact. The results obtained show that the mostimportant characteristics of the contact like minimal film thickness, maximal pressure,axial fluid flow and friction torque can be improved through an appropriate choice oftextures distribution on the contact surface.
