Abstract: The leakage flow characteristics of the variable bristle diameter (VBD) brush seals are numerically investigated using the three-dimensional (3D) tube bundle model with consideration of bristle pack stratification. The ...

Abstract: To accurately predict the leakage flow and resistance characteristics of brush seals, the multiblock structured mesh and the mesh motion technique are applied to the three-dimensional (3D) staggered tube bundle model of ...

Abstract: The helical-labyrinth seal (HLS) can reduce rub between labyrinth teeth and rotor during the rotor vibration because the helical teeth on the stator and steps (or teeth) on the rotor are staggered in some positions. The ...
