RISInlet Preswirl Effects on the Leakage and Dynamic Characteristics of a Labyrinth Seal: Experimental Results and Computational Fluid Dynamics Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fluid-induced forces generated by annular gas seals have aroused considerable attention owing to their substantial impact on the rotordynamic stability of turbomachinery. Positive preswirl at the seal entrance has been ...
Rotordynamic Characteristics of a Novel Labyrinth Seal With Swirl Brakes at Seal Entrance and Cavity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Annular gas seals used in turbomachinery are key elements to ensure a high machine efficiency, due to their effect on the leakage flow. As the most common type of annular gas seals, labyrinth seal is widely used as end and ...
