Many studies about the vibration of rotating vane of turbine had been performed. As in this paper, it was observed on a centrifugal pump operation that stationary part, ring-hat disk vane was vibrating, then it was studied that a mechanism of the phenomena was presumed from the vibration mechanism of turbine vanes.he experimental studies by using actual pump and analytical studies were performed. It was made clear that the interference between pump vanes and pump volute water cuts generate turbulence...

Cause and Countermeasure of Stationary Disk Vibration Damage in Centrifugal Pump

Several estimation methods based on round-robin experiments and/or actual plant experiences have been used to estimate e rosion by liquid drop impingement (LDI). However, in recent years, due to developments on computer technology, it is poss ible to utilize large scale computational analyses. This study proposes a method for the evaluation of LDI erosion by me ans of computational fracture analysis using results (diameters, velocity, or speed of drops) of fluid dynamics analysis....
