Abstract: It is well known that for a reduced Reynolds number (Re*=ρVH/μ⋅H/L) greater than unity, inertia forces have a dominant effect in the transport equations, thus rendering the classical lubrication ...

Abstract: In the current paper, the threedimensional air flow evolution around a circular cylinder is studied. The main aim is to control the flow field upstream and downstream of a circular cylinder by means of radial deformation. ...

Abstract: Some non contacting mechanical face seals are running near the laminar boundary flow limit. A modification of operating conditions leads to a non laminar fluid flow in the seal interface while ...

Abstract: In this paper, the influence of the design and operating parameters on the TEHD behavior of Mechanical Face Seals (MFS), in steady dynamic tracking mode, is analyzed for two different types ...

Abstract: After a short presentation of state-of-the-art experimental studies on the thermal behavior of non-contacting face seals, the literature about numerical models for thermal effects is investigated. ...

Abstract: In this paper, the results of the standard percussion cup test, the penetration cone test, and the laboratory vane test performed on organic sediments and kaolin are discussed. First, the relationship between the water ...

Abstract: The characteristics of hydrostatic bearings can be influenced by the compensating device they use, for example, a thin-walled orifice (diaphragm). The flow through the orifice is given by a law ...

Abstract: It is demonstrated that reactions for impulsive loads in saturated sand soil are speed dependent and can be far higher than the reactions for the corresponding slow loads. The reason is that soils rupture and pore water ...

Abstract: In this study, the seal is supposed to operate in laminar flow, under steady-state conditions and without phase changing in the lubricant film. The model tackles the three-dimensional general ...

Abstract: Even if water has more favorable thermal characteristics than oil, its use in the realm of bearings is still restricted to some rare applications. Moreover, the presence of water in lubricating circuits is seen as not at ...
