    Influence of Slight Gravitational Effect on the Characteristics of Onset Speeds of Instability and Stability in the Vertical Rotating Shaft Supported by Journal Bearing

    In rotating machinery such as vertical pumps supported vertically by sliding bearings, it is difficult to predict the dynamic characteristics because of the strong influence of the nonlinearity of the sliding ...

    Modeling of the Divergently Worn Annular Seal for the Two-Way Coupled Fluid–Structure Interaction Analysis of Shaft Vibration and Clearance Flow

    One of the causes of shaft vibration in turbomachinery is the rotordynamic (RD) fluid force. RD fluid force has a significant impact on the stability of the system, so it is necessary to carry out shaft vibrat...
