摘要：
The dynamic characteristics of the annular pressure seal employed in pumps are theoretically deduced with consideration for the effect of eccentricity of rotor. Turbulent flow is assumed in both circumferential and axial directions, and effect of inertia of the fluid is considered. An equation for the pressure increment due to journal translation is derived in terms of the effective viscosities, based on the rotational and axial flow Reynolds numbers. Stiffness, damping and add mass coefficients are derived. It is shown that the numerically obtained value is in reasonable agreement with experiment.
