Effects of Splitter Blades on Deep Well Pump Performance
Journal of Energy Resources Technology, Transactions of the ASME, 2007 Impellers with splitter blades have been used in turbomachinery design for both pumps and compressors. Increasing the number of blades increases the head of the pump, however, it causes a decrease in efficiency due to the blockage effect of the blade thickness and friction.

Energy saving in a deep well pump with splitter blade
Energy Conversion and Management, 2006 Abstract Design parameters, like blade number, blade outlet angle and impeller outlet diameter, affect pump performance and energy consumption. Deep well pumps with splitter blades (DWPwsb) are manufactured to achieve energy saving and improve efficiency. Splitter blades are generally located at the centerline of the main blades.

3D Inverse Method for Turbomachine Blading With Splitter Blades
Volume 1: Aircraft Engine; Marine; Turbomachinery; Microturbines and Small Turbomachinery, 2000The use of a full 3D and viscous inverse method for turbomachine blading with splitter blades is demonstrated by carrying out a design modification of a transonic axial stator blade row with splitter blades. In this design modification study, the goal is to improve the aerodynamics of the full blade and the splitter blade, including weakening of shock ...

Short Ducted Fan Diffusers With Integral Splitter Blades
Volume 13C: Turbomachinery — Deposition, Erosion, Fouling, and Icing; Design Methods and CFD Modeling for Turbomachinery; Ducts, Noise, and Component Interactions, 2023Abstract To maximise the range of vertical take-off and landing (VTOL) aircraft, the hover efficiency of ducted fan propulsors should be optimised. Diffusers at the outlet of ducted fans increase thrust, for a given power input, by converting otherwise wasted kinetic energy into a static pressure rise.

A Blade-to-Blade Solution of the Flow in a Centrifugal Compressor Impeller with Splitters
Journal of Engineering for Power, 1980The matrix through flow analysis is used to predict the blade-to-blade flow in a centrifugal compressor impeller which contains splitters (half vanes). The presence of solid boundaries in the flow field and the stagnation points associated with it are treated by assuming that the flow around the stagnation point is isentropic.

Splitter Blades for Passive Turbomachine Flutter Control
1993Splitter blades as a passive flutter control technique is investigated by developing a mathematical model to predict the stability of an aerodynamically loaded splattered-rotor operating in an incompressible flow field. The splitter blades, positioned circumferentially in the flow passage between two principal blades, introduce aerodynamic and/or ...
