(Texas A&M University, 2004-09-30)This thesis presents numerical predictions for the leakage and direct stiffness coefficients of pocket damper seals. Modifications made to earlier flow-prediction models are discussed. Leakage and static pressure measurements ...
-
(2012-07-16)This research compares the leakage and rotordynamic characteristics of a slanted-tooth labyrinth seal to a conventional straight-tooth labyrinth. Detailed results comparing the rotordynamic coefficients and leakage parameters ...

(2017-12-11)Understanding the rotordynamic and leakage characteristics of gas annular seals is important for the design of efficient and reliable turbomachinery. This work sets the foundation to advance the understanding of gas ...
-
(Texas A&M University, 2005-11-01)Rotordynamic instability can be disastrous for the operation of high speed turbomachinery in the industry. Most ??instabilities?? are due to de-stabilizing cross coupled forces from variable fluid dynamic pressure around ...
-
(2012-02-14)Tests are performed on a flexure-pivot-pad tilting-pad bearing with a series integral squeeze film damper in load-between-pads configuration, with both active and locked damper. The damper effects are negated when locked, ...
-
(2017-11-28)The author conducts tests using a smooth annular seal with a radius of 101.6 mm (4.00 in) with three radial clearances (0.127, 0.254 and 0.381 mm) referred as 1X, 2X and 3X respectively, producing the radial clearance to ...
