Impact of Skew Vane Cut on Alternating Stress in a Low Specific Speed Radial Pump Impeller Vane Using Fluid-Structure Interaction (FSI) Simulations

Rajavamsi Gangipamula, Ashish Prajapati, Ravindra Birajdar, Shyam Shukla
Proc. ASME. FEDSM2021, Volume 2: Fluid Applications and Systems; Fluid Measurement and Instrumentation, V002T03A037, August 10–12, 2021
Paper No: FEDSM2021-65734
DOI: https://doi.org/10.1115/FEDSM2021-65734
.... pressure pulsations in a pump is the occurrence of the wake flow near impeller trailing edge. At off-design conditions, the Keywords: Rotor-Stator Interaction, Pressure pulsations, flow separation in the pump further broadens the wake flow hydraulic forces, Jet wake flow, blade pass frequency. and hence...
