Abstract EN
Flow condition was simulated in a shaft tubular pump by using the Shear-Stress Transport (SST) k-ω turbulence model with high quality structured grids in design condition.
Corresponding structural vibration characteristics were then analyzed based on two-way coupled Fluid-Structure Interaction (FSI) method.
Fluid results showed that flow in the outlet flow passage was a combination of the axial flow and circumferential rotation motion.
Time and frequency domain analysis of pressure pulsation of typical measure points indicated that larger pulsation amplitudes appeared in the tip of the blades and the main vibration source was the pressure pulsation induced by rotation of the blades.
The fluid pulsation amplitudes decreased gradually along the flow direction, which can be ascribed to the function of fixed guide vane.
Structural analysis of the blades in both pressure and suction side indicated that significant stress concentration was formed at the blade and hub connection near the leading edge.
Maximum effective stress of the blades varied periodically, so prevention measures of the fatigue of blades should be taken.
This research can provide important reference for the design of the tubular pump.
