Journal ArticleDOI
On the Dynamic Properties of Pump Liquid Seals
Alexandrina Untaroiu,Vahe Hayrapetian,Costin D. Untaroiu,Houston G. Wood,Bruno Schiavello,James McGuire +5 more
TL;DR: In this article, the authors presented the linearized rotordynamic coefficients for a liquid seal with large aspect ratio subjected to incompressible turbulent flow, and used these coefficients to predict the rotor dynamic behavior of an industrial pump.
Journal ArticleDOI
Dynamic response analysis of balance drum labyrinth seal groove geometries optimized for minimum leakage
TL;DR: In this article, the rotordynamic coefficients of the labyrinth seal were investigated for their effect on pump rotordynamics due to the large cross-coupled forces generated when the fluid is squeezed by an oscillating rotor.
Proceedings ArticleDOI
Dynamic Response Analysis of Balance Drum Labyrinth Seal Groove Geometries Optimized for Minimum Leakage
TL;DR: In this paper, the rotordynamic coefficients of the labyrinth seal were investigated for their effect on pump rotordynamics due to the large cross-coupled forces generated when the fluid is squeezed by an oscillating rotor.
Proceedings ArticleDOI
Fluid-Induced Forces in Pump Liquid Seals With Large Aspect Ratio
Alexandrina Untaroiu,Vahe Hayrapetian,Costin D. Untaroiu,Paul E. Allaire,Houston G. Wood,Bruno Schiavello,James McGuire +6 more
TL;DR: In this article, the authors present a method to calculate the linearized rotor-dynamic coefficients for a liquid seal with large aspect ratio (balance drum) subjected to incompressible turbulent flow by means of a three dimensional CFD analysis to calculate fluid-induced forces acting on the rotor.
Proceedings ArticleDOI
CFD-Aided Hydraulic Development of a Steam Generator Feed Pump
TL;DR: A rerated single-stage, double-suction nuclear reactor steam generator feed pump, rated at 8,850hp1 for two-pump operation and 13,300 hp for emergency single-Pump operation, underwent fluid dynamic design improvements to achieve satisfactory operability and performance, especially at flow rates below the rated flow of 13,865 gpm2 when running at 4850 rpm.
