RISRotordynamic Performance of a Negative Swirl Brake for a Tooth on Stator Labyrinth Seal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the late 1970s, Benckert and Wachter (Technical University Stuttgart) tested labyrinth seals using air as the test media and measured direct and crosscoupled stiffness coefficients. They reported the following results: ...
Experimental Study of the Leakage and Rotordynamic Coefficients of a Long-Smooth Seal With Two-Phase, Mainly Oil Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper experimentally studies the leakage and rotordynamic performance of a long-smooth seal with air–oil mixtures. Tests are performed with inlet gas-volume-fraction gas volume fraction (GVF) = 0%, 2%, 4%, 6%, and ...
