(Texas A&M University. Libraries, 1988)A new analysis procedure which solves for leakage, reactive force, and rotordynamic coefficients of eccentric annular liquid and gas pressure seals is presented in this dissertation. This analysis procedure is based on a ...
-
(Texas A&M University. Libraries, 1988)The Mach number definition and boundary conditions in Nelson's nominally-centered, annular gas seal analysis are revised. A method is described for determining the wall shear stress characteristics of an annular gas seal ...
-
(Texas A&M University. Libraries, 1984)By employing the extended Hamilton principle, both equations of motion and associated boundary conditions are derived for three different models subjected to non-conservative torques: the cantilevered rotor, the uniform ...
-
(Texas A&M University. Libraries, 1980)This dissertation considers the problem of the foundation force of an unbalanced rotating machine from both deterministic and probabilistic viewpoints. The rotor-housing is modeled as a three degree-of-freedom system wherein ...
-
(Texas A&M University. Libraries, 1993)This research focuses on designing effective control strategies using piezoelectric actuators for control of vibrations of flexible rotor-bearing systems. The actuators are completely described and the elements of feedback ...

Thermoelastohydrodynamic tilt pad journal bearing simulation and application to rotor-bearing model (Texas A&M University. Libraries, 1993)A general approach for incorporating heat transfer and elastic deformation effects into a tilt pad journal bearing simulation model is presented. A global analysis method is used, which includes variable viscosity and heat ...
-
(Texas A&M University. Libraries, 1990)The current numerical model takes into account the full three-dimensionality and cyclic fluctuations of the flow variables in a turbomachinery stage. The cyclic fluctuations are the result of circumferential irregularities ...
-
(Texas A&M University. Libraries, 1989)A general method of incorporating pad flexibility effects into isothermal tilting pad bearing analysis is developed. The pad assembly approach is extended using two-dimensional finite elements to determine pad deformations ...
