<b>Abstract.</b> This paper deals with a finite element analysis of spiral groove gas face seals operating at high speeds. A high-order finite element procedure, based on the Galerkin weighted residual method, is implemented to predict some static and dynamic performance characteristics of grooved gas face seals. Seal opening force, flow rate and dynamic force coefficients are computed with respect to the seal face static misalignment. Curves of seal characteristics depict the influence of the seal face misalignment on the behavior of grooved gas face seals.
