The application of various modifications such as micro-channels, compartments, micro-
pores, texturing in mechanical non-contacting seals causes changes of dynamic properties …

Face seals are typically designed to be in contact at standstill. However, as speed and
pressure build up, the seal faces deform from their factory flat conditions because of viscous …

A numerical model is developed for the dynamic analysis of gas lubricated spiral groove
face seals. Effects of the rotor runout, misalignment, face contact, as well as the stiffness and …

A novel semi-analytical formulation is presented for the linearized dynamic analysis of spiral-
grooved mechanical gas face seals. The linearized rotordynamic properties of the gas film …

The monitoring of abnormal states of dry gas seals is a critical but challenging task for
equipment reliability. This paper proposes an end-face groove structure oriented to the …

Modern I C. Engines are expected to strictly adhere to efficiency standards and to be
ecofriendly. Among the several factors, oil consummation and frictional power losses play …

The effects of lubricant's non-Newtonian property on dynamic characteristics of spiral groove
liquid film seal are presented in this paper. The modified dynamic Reynolds equation for non …

The current research on secondary O-ring seals used in mechanical seals has begun to
focus on their dynamic properties. However, detailed analysis of the dynamic properties of O …

The remarkable nonlinearity of the gas face seal system is partly due to the complex friction
states between the auxiliary seal and the contact pair. In this paper, the transition law …

A properly designed mechanical face seal must satisfy two requirements:(1) the seal must
be stable, and (2) the seal forced response must be such that the stator tracks the …
