... 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...
