Introduction to Splitter Blade

The shape of impeller blades of a centrifugal pump affects the best efficiency point (BEP), and splitter blades improve the pump performance at BEP.

This paper aims to clarify the mechanism of liquid acting on runner blades, the hydraulic performance, and energy conversion characteristics in the runner domain of an impulse water turbine with a splitter blade by using experimental tests and numerical simulations.

Further, the effects of blade number, splitter blades and dimensionless geometric parameters on the mixed-flow compressor performance are investigated by an improved loss model.

This study strive for investigating the impact of splitter blade on pump as turbine performance considering different speed and flow rates.

This study takes the splitter blade as the object of structural improvement.

With the development of smart power grid, pumped storage has been developing on a large scale, and the pump-turbine with splitter blades is widely used.

For this purpose, the effect of splitter blades on slip factor distribution to improve the pump head was investigated using numerical simulation tools and validated based on experimental test data.

The application of splitter blades can improve passage obstructions and reduce flow loss of small-scale organic Rankine cycle (ORC) radial inflow turbines.

Type 2 vortices had the same length as Type 1, but they were discharged from the splitter blade.

Starting from a baseline design, through changing design variables such as blade angles, blade thickness, and position of splitter blades.

Influence of the splitter blades can be also observed in both time and frequency domain of measured instantaneous velocities.

Blades number Z, bias angle in peripheral direction of splitter blades θs, inlet diameter of splitter blades Dsi, and deflection angle of splitter blades α were selected as the main factors in orthogonal test.

To expand the stable operating range of a 200 m head Francis turbine, splitter blades were designed to increase the cavitation ability and lower the high-amplitude pressure fluctuations.

An investigation into rotor blading shows favorable performance gains through the inclusion of splitter blades.

This paper reveals a novel design of centrifugal compressor impeller with multisplitter blades for performance improvement.

Most studies on cryogenic turboexpanders are focused on parametric studies and mean-line design to increase the performance of cryogenics liquefaction cycle without much attention to the splitter blades which are crucial for the stability of the flow field.

The present article developed a hybrid optimization model based on genetic algorithms (GA) and a 3D simulation of compressors to examine the certain parameters such as blade angle at leading and trailing edges and the starting point of splitter blades.

The blood pump with good hemolytic and anti-thrombogenic property at widely operating range was designed by developing a structure that including the spindly rotor impeller structure and the diffuser with splitter blades and cantilevered main blades.

The influence of the blade profile, blade tip width, blade numbers and splitter blades on the hemodynamic characteristics through the pump is observed.

In this paper, a high speed radial micro turbine with the splitter blade was designed for a 40 L/h helium liquefier with Claude cycle.
