Abstract: Taking the flow field features of labyrinth seal into consideration, the fluid force generated from the seal cavity, which is spatially separated into two regions, is modeled with the perturbation method. The rotor orbit ...

Abstract: The aim of this work is to present a technical numerical method to improve the efficiency of solving the Reynolds equation for hydrodynamic bearings. Hydrodynamic bearings are largely employed in the shafting of high-speed ...

Abstract: Hysteresis exists widely in intelligent materials, such as piezoelectric and giant magnetostrictive ones, and it significantly affects the precision of vibration control when a controlled object moves at a range of micrometers ...

Abstract: In order to broaden the sound absorption bandwidth of a perforated panel in the low frequency range, a lightweight membrane-type resonator is installed in the back cavity of the perforated panel to combine into a compound ...

Abstract: The cutback film cooling was important to decrease the trailing edge temperature and prolong the working life of gas turbines. Many investigations concerning cutback film cooling have already been done. However, only a few ...

Abstract: This article presents an investigation of dimples and protrusions arranged on the end wall of a rotor blade to enhance heat transfer. This study explores three arrangements of dimples and protrusions relative to the pin-fins, ...
