... dimensional RANS equations solutions were utilized to investigate the conjugate heat transfer characteristic in the straight-through labyrinth seal with and without rub damages. The influence of bending and mushrooming damages on the Nu distributions on the seal rotor and stator surfaces were computed...

... rotor bending vibrations coupled with a one-nodal (k = 1) blade system. Rotor-blade coupled bending conditions generally include two types so that the parallel and tilting modes of the shaft vibrations are respectively coupled with in-plane and out-of-plane modes of blade vibrations with a one-nodal...

... Americas, 19th Annual Conference on Liquid Atomization and Spray Systems] . We compare simulation results obtained using a liquid to gas density ratio of 10 and 100. The results show that the increase in density ratio causes a noticeable increase in liquid core penetration with reduced bending...

...Onome E. Scott-Emuakpor; Herman Shen; Tommy George; Charles Cross A new energy-based life prediction framework for calculation of axial and bending fatigue results at various stress ratios has been developed. The purpose of the life prediction framework is to assess the behavior of materials used...

... are used to reduce the rotor mass and increase bending critical speed. Therefore, the model developed in this paper assumes that the rotor is a hollow shaft. The heat transferred to the rotor from the air film travels through the rotor shell by conduction, and then is convected from the rotor surface...

...Cesare Guardino; John W. Chew This paper presents a new method for predicting the three-dimensional (3D) bending behavior of bristles in brush seals. The model builds on and addresses shortcomings in an earlier two-dimensional bending model. The work was motivated by the need to develop a general...
