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 ...
Influence of mainstream turbulence and unsteady wake on turbine blade heat transfer
(1993)
The influence of mainstream turbulence and unsteady wake on turbine blade surface heat transfer was studied. The experiments were performed with a five-blade linear cascade in a low speed wind tunnel facility. The wake and ...
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 ...
Local heat transfer in an enclosed corotating disk with axial throughflow
(1992)
Local heat transfer in an enclosed corotating disk with axial throughflow was investigated. The rotating cavity has two plane disks and a cylindrical rim (shroud). The ratio of the rim span to the disk outer radius is 0.4 ...
