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 ...

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 ...
