In recent years, much attention has been paid to the application of high-speed centrifugal pumps; still, development this pump faces several challenges. order obtain a more comprehensive understanding pump, paper reviewed engineering application, technical challenges, and feasible solutions from aspects hydraulic design, including cavitation, excitation, efficiency issue at an ultra-low specifi...

This paper concentrates on cavitation detection using discrete wavelet transform by classifying the pump vibration signal. Vibration signal acquired from centrifugal pump cavitation test rig carry more information about the cavitation classes. In this paper two classes has been defined namely, no cavitation class and developed cavitation class. This method uses the deviation from zero mean valu...

For the centrifugal pump, rotor–stator interaction (RSI) induces high-energy pressure pulsation, which directly affects stability of systems and equipment. Therefore, this work proposes a new staggered impeller structure to suppress pulsation in pumps. The original blade is divided into two layers at 10°, 20° 30° form impeller. dynamic characteristics both are predicted using large eddy simulat...

In contrast to conventional generators, self-excited induction generators are found to be most suitable machines for wind energy conversion in remote and windy areas due to many advantages over grid connected machines. This papers presents a Self-Excited Induction Generator (SEIG) driven by wind turbine and supplying an induction motor which is coupled to a centrifugal pump. A method to describ...

Left ventricular assist devices (LVADs) are increasingly used for the treatment of end-stage congestive heart failure, both as a bridge to transplantation and as destination therapy (1). The HeartWare HVAD (HeartWare Inc, Framingham, MA, USA) is a continuous centrifugal-flow left ventricular assist device with a magnetic levitating rotor pump. The pump weighs just 140 g and its small design all...

Centrifugal pumps are designed to have their BEP (Best Efficiency Point) for a given flow rate, hydraulic head, and speed. In the design phase, those parameters combined into dimensionless specific speed used define geometry of pump. this paper, downsized centrifugal pump has been high efficiency at very speeds (10000 – 15000 RPM), as requested by cooling circuit an engine motorsport racing app...
