Abstract
The computational model is based on the dependence of viscosity and permeability of the porous layer of the pressure-layer hydrodynamic lubrication
Incoming article date: 09.04.2014In this paper, based on the Navier-Stokes equations , the continuity equation , taking into account the pressure dependence of viscosity , Darcy equation taking into account the dependence of the permeability of the porous layer of the pressure given by the exact method of forming a self-similar solution of the problem of calculating the hydrodynamic journal bearing operating at three-layer lubricant . As a result, found the velocity field and the pressure in the lubricating layer and the analytical expressions for the components of the supporting forces and friction. Found rational bearing capacity values characterizing different aspects of the functioning of the knot of friction , namely profile support surface ; special lubricating fluid interaction with the surfaces of the friction unit , taking into account the pressure dependence of viscosity ( the formation of intermediate layers with different lubricant viscosities ) .
Keywords: three-layer lubrication, maintenance force adapted profile stratified flow.
