摘要：
A newly-developed stern tube seal, which consists of two segmented carbon seals and two lip seals, has been evaluated. Fundamental air leakage tests under stationary conditions through very narrow clearances are presented. A theoretical analysis was carried out with cylindrical models in order to clarify the seal performance. The flow patterns were also visualized using simplified models. Analysis that included viscous friction, fluid inertia and losses at inlet and outlet under subsonic or choked flow was found to correlate well with the test results.
