The numerical algorithm for the analysis of three-dimensional PEHL used in this study has advantage that the pressure and film distributions can be calculated from Reynolds equation for all mixed lubrication region without any specific boundary condition for the edge of solid contact region. Using the developed PEHL algorithm, we calculated the distributions of pressure and film thickness for the surfaces with bi-modal sine waviness at present and with single-modal crowning waviness we suggested. It is shown that the surface with the single-modal crowning waviness is more beneficial to the development of film than that with the bi-modal sine waviness.
