RISStudy on Damping of Nozzleless Radial Turbine and Its Role in Forced Response
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This paper systematically investigates the factors influencing radial turbine damping, including aerodynamic and material damping. Aerodynamic damping is identified as the dominant contributor, accounting for ...
New Evaluation Method for Liquefaction of Ground Using Dynamic Liquefaction Analysis Method and Its Application
Publisher: American Society of Civil Engineers
Abstract: Nankai megathrust earthquakes are expected to occur with a return period of approximately 90–200 years along the fault of the Nankai Trough. Because they are interplate earthquakes, it is predicted that they will cause ...

Blade Excitation Alleviation of a Nozzleless Radial Turbine by Casing Treatment Based on Reduced-Order Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High cycle fatigue (HCF) is the most common form of blade failure in nozzleless radial turbines. Current studies relating to blade vibration reduction focus on redesign of blade and volute geometries. These methods have ...
Development of Boiling Water Reactor Steam Dryer Loading Evaluation Methods Through Scale Model Tests Under Actual Steam Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Previous plant measurements and scale model tests have demonstrated that intense fluctuating pressure acted on the steam dryer in boiling water reactors (BWRs) at higher velocity flows than in normal operation. The cause ...
