Abstract
This paper is devoted to the analysis of effects of the dimple geometry on the hydrodynamic characteristics of a tilting pad thrust bearing.In a first step a discretization of Reynolds equation has been carried out by the finite difference method.It is followed by the development and validation of a hydrodynamic model used later for the examination of the influence of different surface dimples (radial, circumferential, rectangular…) on the hydrodynamic characteristics such as maximum pressure, friction torque and power loss.This study allowed highlighting that a suitable arrangement of the dimple contact surface area and also the depth of the dimple can contribute significantly to the improvement of the hydrodynamic characteristics of the tilting-pad thrust bearing.
