Abstract

In the paper, static characteristics of spiral grooved seal is theoretically obtained by Using Navier-Stokes equation. In the analysis, inertia term of fluid is considered and the flow and pressure in the steady state are obtained for the groove direction and vertical to the groove direction. As the journal rotating frequency increases, the leakage flow decreases. Therefore, zero net leakage flow is possible at the region of some rotating frequency.
