Integral Relationships in the Planar Problem of Gas Lubrication and Some of Their Applications,

Abstract

On the basis of equations analogous to Prandtl equations in the boundary layer theory, integral correlations valid under arbitrary movements of the journal and bearing centers are derived in a compact form, expressing the laws of mass variation, momentum, and energy in a two-dimensional layer of unit length of an isothermic lubricant. As an example of the application of the correlations the case of the steady-state motion of the lubricant is discussed, and a system of ordinary differential equations valid at any Reynolds number is set up for determining the pressure in the layer and the friction forces on the journal and the bearing. The approximate solution of these nonlinear equations is presented. (Author)
