Numerical Analysis of Thermoelastohydrodynamic Behavior of an Elliptical Tow-Lobe Bearing

Abstract:

In this paper the thermoelastohydrodynamic study for analysis of elliptical journal bearing (Two-lobe) operating with Newtonian lubricant has been presented. The thermo-elastic deformations of the solid parts are taken into account. To solve the Reynold's equation generalized, equation of energy and the displacement field, respectively, using two numerical techniques Computational Fluid Dynamic "CFD" and Fluid Structure Interaction "FSI". The "CFD" is used to determine the pressure, temperature and velocity fields in the lubricant film, the stress intensity and displacement field is obtained by "FSI" simulation. The influence of the operate conditions on the fields pressure, temperature displacement and stress intensity is also analysed.
