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 …

Study on the Method of Calculation of the Additional Mass of Parachute
Abstract: As is well known, the air drag experienced by a parachute when it is open is one of the important parameters that must be taken into account in studying the parachute opening process. If this term is not calculated correctly, it can have a negative effect on the parachute canopy, and may lead to errors in the number of parachute strings, the nominal diameter of the parachute, and the material …

A Method of Mesh Deformation for Flow Analysis Around Oscillating Bodies
Abstract: In general, high-speed rotating machines are subjected to complex phenomena due to various reasons, such as increased noise and strong vibration due to dynamic unbalance, which affect the dynamic motion of rotating machines and are necessarily a problem to overcome. Therefore, it is necessary to have a mathematical model to simulate it, and a strong tool to solve the constructed model. Using fluid-structure coupling techniques, which are currently a powerful …
