RISAnalysis of Eccentric Annular Incompressible Seals: Part 2—Effects of Eccentricity on Rotordynamic Coefficients
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In Part 1 of this paper, a new analysis procedure is presented which solves for the flow variables of an annular pressure seal in which the rotor has a large static displacement (eccentricity) ...
Analysis of Eccentric Annular Incompressible Seals: Part 1—A New Solution Using Fast Fourier Transforms for Determining Hydrodynamic Force
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new analysis procedure is presented which solves for the flow variables of an incompressible-flow annular pressure seal in which the rotor has a large static displacement from the centered ...
Fail-Safe Optimal Design of Complex Structures With Substructures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the problem of fail-safe design of complex structural systems is considered. A substructural formulation for this class of design problems is presented. Constraints are imposed ...
Comparison of Hirs’ Equation With Moody’s Equation for Determining Rotordynamic Coefficients of Annular Pressure Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rotordynamic coefficients of an incompressible-flow annular pressure seal were determined using a bulk-flow model in conjunction with two different friction factor relationships. The first, ...
