Abstract

In this study, hydrodynamic characteristics of laminar fluid flow between two eccentric rotating cylinders with finite length is investigated. The analysis is based on the numerical solution of the full Navier-Stokes equations using CFD techniques. Considering the complexity of the physical geometry, conformal mapping is used to generate an orthogonal grid and the governing equations are transformed in the computational domain. Discretized forms of the transformed equations are obtained by control volume method and solved by SIMPLE algorithm. The numerical results of this analysis can be used to investigate the oil flow pattern in the journal bearings. To validate the computational results, comparison with the experimental data of other investigators is made, and reasonable agreement is found.
