摘要:
This paper describes the finite-element solution of the nonlinear and coupled hydrodynamic and thermal equations for pressure and temperature profiles in an oil seal including misalignment. Fluid properties are evaluated at the center of each element. For centered seals, results obtained are in good agreement with previous finite-difference analysis with approximate temperature distribution. For eccentric or axially tapered seals, use of the true temperature profile gives significantly different results. This analysis shows that the circumferential temperature variation should be considered in oil seal analysis and that reducing clearance taper produces a stabilizing effect.Presented at the 48th Annual Meeting in Calgary, Alberta, Canada May 17–20, 1993
