The present paper investigates the dynamic behaviors of a bubble restricted by two parallel
plates near an elliptical wall. The typical experimental phenomena of the bubble are …

Active bearings (including fluid film bearing) are efficient in reducing vibration and improving
dynamic performances of rotary machinery. The control systems have significant influence in …

Rotating machines are elements of great importance to the production chain, and they can
eventually operate under unpredicted or off-the-norm conditions, thus causing failure and …

Oil film vortex severely reduces the stability of hydrostatic bearings. A solid-liquid interface
with drag and slip properties can weaken the oil film vortex of the bearing. Here, a combined …

Bearings are the significant component in machinery applications to run a system; hence,
the damage of bearings can stop a running machine. The bearing faults often arise because …

Several researches on hydrodynamic bearings has looked for alternatives to increase their
performance. Solutions involving modifications in oil feeding grooves and bearing geometry …

In order to address the problems of insufficient load capacity and rotor vibration, an active
fluid-film bearing lubricated with magnetorheological fluid (MRF) is proposed. First, the …

Various processes take place in rotor systems with tilting pad bearings. It is important not
only to control but also to manage these processes. Due to the instability of the oil film layer …

Obtaining the best operating parameters of the internal combustion engine has focused the
attention of designers and researchers since the first years of its creation. Initial research …
