Abstract
Apart from the function such as micro-hydrodynamic bearings, lubrication reservoir and debris traps, surface textures can be used to control the lubricant׳s flow. In this paper, the leak control feasibility is numerically validated by processing some different oriented dimples on the mechanical seals, including the elliptical, diamond, triangular and rectangular shapes. The streamline-Upwind/Petrov-Galerkin (SUPG) finite element method is used to solve the Reynolds equation by considering mass conservation. Parametric study is performed to analyze the effect of the geometric parameter on the sealing performance such as the flow rate and the load-carrying capability. The reverse pumping capability is compared among these oriented dimples.
