Abstract: A vibration absorber (designated as the Super Dynamic Damper) for installation on ship superstructures, based on a tuned centrifugal pendulum concept, was developed through theoretical analyses ...

Abstract: Unsteady flows around radial impellers are analyzed by the use of singularity methods. Unsteady torque is given for transient and/or sinusoidal flow rate and/or angular velocity fluctuation. It ...

Abstract: Rotating cavitation was analyzed using an actuator disk method. Quasi-steady pressure performance of the impeller, mass flow gain factor, and cavitation compliance of the cavity were taken into ...

Abstract: This paper describes the analysis of J -integral and crack growth for the surface cracks in work-hardening bodies. First, the complementary energy method has been formulated, which evaluates the ...

Abstract: This paper investigates the performance of a seal system for an aerostatic journal bearing used in a high vacuum chamber. The seal system consists of axially spaced viscous seals and annular ...

Abstract: In the previous linear analysis (Tsujimoto et al., 1993) it was found that there can be a backward rotating cavitation as well as a forward mode which rotates faster than impeller. Although ...

Abstract: A catalytic combustion system has high potential to achieve low NOx emission level. When this combustion system is applied to a gas turbine, the required combustor performance must be maintained ...
