A Lubrication Analysis of Gas Mechanical Face Seals using a High-Order Shape Function
고차 형상함수를 이용한 가스 미케니컬 페이스 시일의 윤활해석
Abstract
For the treatment of high compressibility number in the Reynolds equation, a new class of exponential high-order shape functions has been recently introduced in the literatures. In this paper a FE lubrication analysis method of high speed gas mechanical face seals is developed, implementing these shape functions. Their validity and usefulness are presented using 1-D gas bearing models. And a validation of developed 2-D analysis code is shown with a gas flat and spiral groove face seal models.
