A comparison between two numerical techniques for hydrodynamic journal bearing problems

Abstract Algorithms for two solution techniques, namely the Gauss-Siedel iterative scheme and the linear complementarity problem (LCP) approach, for finding the positive pressure region in a hydrodynamic journal bearing-lubricant flow field are presented. In the LCP approach the necessity for partitioning the matrices, as suggested in the earlier published works, is avoided. The two techniques are compared through the results and computer time for plain and two-axial groove journal bearings operating in laminar flow regimes.
