Abstract

The helium compressor is one of the key components in the high temperature gas-cooled reactor coupled with a helium turbine. The aerodynamic performance of the helium compressor significantly influences the whole system efficiency. Therefore, the effects of the tip and axial clearances on the helium compressor need to be further studied and optimized. A computational fluid dynamics model that has been verified against experimental data of the helium compressor is used to investigate the influence of the tip and axial clearances. The results show that a reduced tip clearance reduces the flow losses and increases the compression ratio and compressor efficiency, especially for clearances of less than 0.3 mm (2% of the relative blade height). A larger axial clearance lowers the compressor efficiency with an acceptable axial displacement of ±1.0 mm. The results show the influences of the tip and axial clearances on the model, and provide guidance for the design and optimization of the actual helium compressor.
