Abstract: 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 ...

Abstract: The wear characteristics of the trapezoidal fin against high-speed rotor were experimentally investigated at different final incursion depths, incursion rates, and sliding velocities. To characterize the geometrical effect, ...

Abstract: This study reports an experimental work on friction contact between the chamfered labyrinth fin and high speed rotor at different incursion rates, final incursion depths, and sliding velocities. The small (original design ...

Abstract: The finite element analysis (FEA) and computational fluid dynamics (CFD) methods are utilized to investigate the leakage performance degradations in two kinds of flexible seals (i.e., forward bending and backward bending) ...
