A three-dimensional viscous flow model of stator/rotor interaction in turbomachines
(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 ...
Entrance and exit region friction factor models for annular seal analysis
(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 ...
Load-induced rotordynamic instabilities in turbomachinery
(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 ...
Analysis of eccentric annular pressure seals : a new solution procedure for determing reactive force and rotordynamic coefficients
(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 ...
