System Oscillations Associated With Cavitating Inducers

The nature and inception of pressure and flow-rate oscillations associated with a high-speed cavitating inducer have been investigated by nonlinear analog computer simulation. The favorable accord between simulation findings and typical actual dynamic oscillation characteristics validates the general technique for extension into inducer design analyses. The nature and behavior of the cavitation vapor volume and the dynamic response characteristics of the complete fluid circuit play key roles in the incidence and suppression of oscillations.
