Study of Performance of Splitter-Inducer and Its Aid to Improvement in Performance of High Pressure-Ratio Charger

The authors analyse the effects of splitters on compressor channels by calculation, and present the main factors which have to be taken into consideration when splitters are to be designed. The calculation results of the velocity distribution in compressor channels give the scientific rules for exami- ning the performance of a splitter-inducer. Experiments show that a well designed splitter-inducer can improve the efficiency, raise the pressureratio, and increase the stably running range of a high pressure-ratio charger.
