TL;DR: In this paper, the authors consider the flow of a thin liquid film over a spinning disc in the presence of an electric field and derive a coupled set of evolution equations for the film thickness, radial and azimuthal flow rates and the surface charge density.

TL;DR: In this paper, the optimum design of spherical bearings in fluid film lubrication is examined theoretically and analytical solutions are derived for both fitted and clearance types of bearings with capillary and orifice restrictors.
Abstract: The optimum design of hydrostatic spherical bearings in fluid film lubrication is examined theoretically. The analytical solutions are derived for both fitted and clearance types of bearings with capillary and orifice restrictors. The optimal size based on the minimum power loss and the maximum stiffness is presented, and the difference between two types of hearings is discussed.

TL;DR: In this article, a numerical model was formulated based on transient lubrication theory and modified to include kinetic evaporation and disjoining pressure, and the model uses an ordinary differential equation solver to advance the governing equations in time with staggered finite differences for the spatial derivatives.
