Analysis of Hydrodynamic Characteristics of a Squeeze Film in O-Ring Assembly Under the Oscillating Motion
Abstract: In the most of the non-contacting face seals, squeezing occurs in the fluid film between the O-ring surface and the mating surfaces in the gland assembly. Therefore, hydrodynamic characteristics are easily simulated by considering a fluid film between a rubber surface (O-ring surface) and a rigid surface (machined surface). In this paper, effects of surface roughness of rubber block on leakage flow rate and hydrodynamic force developed in fluid film …
