Ko, Sung-Ho (Texas A&M University. Libraries, 1991)This study discusses the derivation and assessment of a new two-scale dissipation equation, the genesis of which begins with a different fundamental equation than previous multi-scale or single-scale models. The new approach ...
-
Xu, Jinming (Texas A&M University, 2007-09-17)The labyrinth seal is widely used in turbomachinery to minimize or control leakage between areas of different pressure. The present investigation numerically explored the effect of damage and wear of the labyrinth seal on ...
-
Suryanarayanan, Arun (Texas A&M University, 2004-11-15)In any rotating machinery, the geometry of the seal influences the extent of systemleakage. The path taken by the flow in the clearance volume is dependent on the seal and rotor profile. The clearance between a new ...

Rhode, David L. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 1993-09-14)An improved design for a labyrinth seal is disclosed. The present invention relates to a radially stepped labyrinth seal whereby the geometry of the sealing surfaces is to optimize flow deflection, thereby producing maximum ...
-
Choi, Dong Chun (Texas A&M University, 2006-08-16)A combination of 3-D and 2-D computational fluid dynamics (CFD) modeling as well as experimental testing of the labyrinth seal with hexagonal honeycomb cells on the stator wall was performed. For the 3-D and 2-D CFD models, ...

Demko, Jonathan Alexander (Texas A&M University. Libraries, 1986)A computational/experimental study was conducted on the incompressible flow in a labyrinth seal at a variety of leakage rates and seal rotation rates. The predictions were obtained using a finite difference code that ...
-
Xi, Jinxiang (Texas A&M University, 2007-04-25)Systematic parametric studies were performed to better understand seal-inlet rotordynamics. A CFD-perturbation model was employed to compute the seal-inlet flow disturbance quantities. Seal inlet disturbance boundary ...
