A New Numerical Technique for the Analysis of Lubricating Films Part 2: Precision and Convergence
Published January 01, 1987 by Institution of Mechanical Engineers in United Kingdom
The Local Partial Differential Equation Method (L.P.D.E.M.) for the numerical computation of film pressure in hydrodynamic bearings is critically examined with respect to precision and convergence. A finite width slider with an exponentially varying gap is used as the test problem. Results of the film pressure and of film flux components, as computed by the conventional Finite Difference Method (F.D.M.) and by L.P.D.E.M., are compared with the exact analytical solution of Charnes and Saibel.
