Computational analysis of coned-face spiral groove gas seals using the finite element method
Keywords:
face seals, grooved seals, spiral grooves, coning effects, gas lubricationAbstract
In this work, an efficient finite element procedure for high speed thin gas film lubrication problems, which is based on the Galerkin weighted residual method with high order shape functions, is employed to analyze the effects of the face coning on spiral groove face seal performance. Opening force, dynamic force coefficients and leakage flow are determined for different face seal coning angles and operating conditions. Finite element predictions bring some insights into the influence of the face coning on gas-lubricated spiral groove face seal performance characteristics at high speeds.
