... Abstract This paper presents a study of the effects of blade pitch angle and inlet guide vane (IGV) angle on the performance of a submersible axial-flow pump. To analyze the interaction effects between the IGVs and the rotor blades, both steady and unsteady three-dimensional Reynolds-averaged...

... A new method is put forward to model the flow in a highly loaded axial flow pump. A directional loss model is utilized to model the function of a valve behind the pump stator vanes. A periodic boundary condition between the inlet and the outlet of the pump is applied to model a closed loop. Thus...

... 30 07 2010 In order to analyze the flow characteristics of a high efficiency axial-flow pump, the behavior of the flow in an adjustable axial-flow pump bas been analyzed by numerical simulations of the entire stage based on Fluent software. The prediction data shows agreement...

... 10 07 2009 In highly loaded axial flow pumps considerable changes of the flow behavior are known when altering the flow rate from design point operation to part load operation. The flow structure which is changing from stable operating conditions to stalled flow conditions has been...

... 26 03 2009 In highly loaded axial flow pumps considerable changes of the flow behavior were reported when altering the flow rate from design point operation to part load operation. The flow structure which is changing from stable operating conditions to stalled flow conditions has been...

... 03 03 2009 When reaching the stall point of an axial-flow pump, the pump head characteristic becomes unstable and the pump head suddenly drops. Before this happens however, at even higher flow rates the NPSH3 and the pump body and shaft vibrations increase dramatically. For effectively...

... 14 10 2008 The article describes numerical research of fluid flow inside an axial-flow pump that includes adjustable guide vanes, impeller and discharge channel. The guide vanes in the extreme position cut off the flow through the pump. The article presents the performance curves...

... 14 10 2008 Different experimental techniques were used to investigate the structure of the rotor tip flow in a highly-loaded single-stage axial-flow pump. Probably the most important result of this investigation is the first-time visualization of a spiral-type vortex breakdown...

... 08 09 2008 An experimental study has been performed on energy characteristics of axial-flow pumps designed for one pumping station in Jiangsu province, China. The energy characteristic tests for two different model runners were carried out. The result shows that the airfoil shape...
