RISInfluence of the Magnitude of the Taper Angle of Divergent and Convergent Tapered Annular Seals on the Stability of a Vertical Rotor-Seal System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rotordynamic (RD) fluid force generated in seals affects the stability of turbomachinery. RD coefficients have been determined using bulk-flow or computational fluid dynamics analyses, and the effect of seals on the ...
An Extended Operational Modal Analysis Method Enabling the Separation of Whirling Direction Information in Rotating Machinery (Full Operational Modal Analysis Method)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Operational modal analysis (OMA) has recently been applied to the condition monitoring of rotating machinery. Conventional OMA is based on a one-dimensional signal. The natural modes of a rotating machinery can be classified ...
Influence of Unbalance and Differential Pressure on the Stability of Vertical Rotor-Seal System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rotordynamic (RD) fluid force generated in fluid elements such as seals in turbomachinery affects the stability of turbomachinery and causes shaft vibrations. Various studies have been conducted to clarify the effects ...
