To perform vibration analysis, many structures could be modeled entirely or partially as
beams with variable or constant cross section. In this study, the differential equations for free …

With a view to enabling additive manufacturing (AM) processes, today, open-source, low-
cost 3D printers are systems with great potential. However there is a significant lack of …

This paper represents the results of calculation of rotordynamics and leakage rate
characteristics of scallop seals with sickle grooves (SSSG) depending on seal geometry …

The hole-pattern damping seal (HPDS) is one of the most typical sealing solutions used in
gas turbines. Structural innovation and geometrical optimization of hole cavity shape of hole …

Performance parameters such as power loss, minimum film thickness, and maximum oil
temperature of the sector-shaped tilting pad thrust bearings employing the new micro …

The inlet deflection angle is an important blade design parameter with respect to both
performance and manufacturability of torque converters. This study investigated the …

In noncontact annular labyrinth seals used in turbomachinery, fluid prerotation in the
direction of shaft rotation effectively increases fluid velocity in the circumferential direction …

Textured thrust bearings are capable of providing higher load capacity and lower friction
torque compared to nontextured bearings. However, most previous optimization efforts for …

Reducing of leakage rate of annular seals is an important objective of sealing technology. A
number of noncontact seals are used for hermetic sealing of centrifugal compressors shafts …

Gas foil bearings can operate in extreme conditions such as high temperature and high
rotating speed, compared to traditional bearings. They also provide better damping and …
