Gas-Lubricated Porous Bearings ---Short Journal Bearings,Steady-State Solution.

摘要

The governing equations for a short porous bearing are derived by adopting Ocvirk's approximation to the general equations for a finite bearing, which are given in a previous paper. Crank-Nicolson's numerical method and the analytical-numerical technique, which consists of Green function approximation and the local smoothing by integration for a Fourier series, developed in another paper are employed to solve the modified Reynolds equation for a wide range of compressibility number. The solution for a solid-wall bearing is obtained as a special case of a porous bearing. Comparison between two thicknesses of porous layer is included.
