...Xin Yan; Xinbo Dai The wear behaviors of the rectangular labyrinth seal fin against high-speed rotor were experimentally investigated on the incursion test rig. The material losses, worn geometries, frictional temperature distributions, and contact forces of labyrinth fin in rubbing events were...

... and turbulence kinetic energy distributions) are almost the same. As Ghasripoor et al. mentioned in Ref. [ 4 ], rubbing in the rotating labyrinth seal tends to round or mushroom the labyrinth fin tip (as shown in Figs. 1( b ) and 1( c ) ). The permanent damages in the labyrinth fin directly lead...

... bearings (DE-, NDE-, and end-bearing) are indicated. Figure 7 shows the rotor dynamic model of the turbogenerator. For a rub with a contact force varying due to inertia effects, this would be the appropriate relation, e.g., in case the inertia forces of the brush masses themselves would play...
