Finite element analysis of the spiral groove dry gas seals

Lin Pei-feng

Abstract

A finite element analysis scheme using a Galerkin weighted residual method for the spiral groove dry gas seals was designed based on Reynolds Equation of compressible gases. And a software was designed for computing the spiral groove dry gas seals on the Visual C + + 6.0 environment. By comparing the computed results with the experiment results, it is proved that the computed results is satisfied.
