| Abstract: | An efficient and accurate finite element procedure was adopted to analyze axial perturbation of gas-lubricated spiral groove face seals operating at high speeds. The procedure is based on the Galerkin weighted residual method with a new class of high-order shape functions. Static and dynamic performance characteristics, such as the seal opening force, flow leakage, dynamic stiffness and the damping coefficients, were calculated for studying the effects of a series of parameters at high speeds on the behavior of spiral groove gas face seals. |
