Regenerative centrifugal pumps (RCP) are the subject of increased interest in industry as these pumps produce less noise, have low specific speed and are compact but capable of delivering high heads with stable performance characteristics. The regenerative flow pumps are essentially rotodynamic turbo machines capable of developing high pressure ratios within a single stage. This paper presents ...

Extracorporeal liver perfusion (ECLP) has been used for detoxifying blood in patients in class IV hepatic encephalopathy. Palliation of the moribund patient utilizing extracorporeal devices with cross-circulation of a cadaver liver has been documented for over three decades. Common problems associated with this procedure which appear in the literature include cadaver liver distention, increas...

Aiming at the problems of low working efficiency and high energy loss in operation centrifugal pump, an intelligent algorithm for pump design was proposed. On basis hydraulic design, a multi-objective optimization mathematical model established. A Genetic (GA) designed to optimize major structural parameters optimal combination obtained. Calculation results suggested that optimized significantl...

Effects of the time-variant flow in a single-blade pump are investigated by numerical and experimental methods. For a numerical approach the three-dimensional, viscous, unsteady flow field in the pump has been achieved by solving the unsteady Navier-Stokes equations (URANS) with a commercial solver. From the obtained periodic flow field the time-variant forces acting at the wetted impeller surf...
