【Abstract】 An efficient and accurate finite element method was proposed to analyze the steady state performance of T shape groove dry gas seals. The method is based on the Galerkin weighted residual method and a discrete equation is derived from the compressible gas Reynolds Equation. The discrete equation was solved by a numerical iteration. A software was developed for computing the T shape groove dry gas seals based on the VC6 0 environment. The computed results well agreed with the experiment results.更多还原
