(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 ...
-
(2017-12-04)Data are available for a previously tested annular seal with no swirl brakes (NSB). The NSB seal design was modified by adding slots at the inlet to produce a swirl brake (SB) seal. Tests were conducted to evaluate the ...
-
(2016-10-10)Fluid forces acting on the shrouded centrifugal pump/compressor impellers are evaluated using the computational fluid dynamics (CFD) approach. A face-seal impeller is selected to study for predicting the rotordynamic ...
-
(2018-10-22)Eccentrically operating turbomachinery components such as impellers and seals are subject to flow induced forces known as rotordynamic forces. Rotordynamic forces can be detrimental to the machine stability and longevity. ...
-
(2021-04-12)The jointing of concrete pavement is intended to provide free movement within the concrete slab. Joint sealing material, called a joint sealant, has evolved in recent decades to prevent or reduce the amount of water from ...

(2009-05-15)In Squeeze Film Dampers, (SFD), grooves (deep or shallow) are used to feed oil into the damper and prevent oil starvation within the fluid film lands. In oil seals with film land of clearance c, short shallow grooves (depth ...

(Texas A&M University, 2007-04-25)Results are presented for measured and predicted rotordynamic coefficients and leakage for hole-pattern seals with a hole depth that varies axially along the seal. Testing was done to discover how pressure ratio, inlet ...
