Sk. Baheti et Rg. Kirk, THERMO-HYDRODYNAMIC SOLUTION OF FLOATING RING SEALS FOR HIGH-PRESSURECOMPRESSORS USING THE FINITE-ELEMENT METHOD, Tribology transactions, 37(2), 1994, pp. 336-346
This paper describes the finite-element solution of the nonlinear and
coupled hydrodynamic and thermal equations for pressure and temperatur
e 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 analysi
s 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 tempe
rature variation should be considered in oil seal analysis and that re
ducing clearance taper produces a stabilizing effect.
