CFD validation and analysis of a single-stage axial compressor

The knowledge about changes of flow field properties during axial compressor operation at high and relatively low speed is limited. This work provides a numerical approach to address these problems. Validations about the numerical scheme and the test of compressor performance at various operating speeds are conducted. The results show that computational fluid dynamics (CFD) is capable in predicting the compressor performance. Flow property changes during the compressor operation are discussed and explanations are proposed. This work reinforces the understanding of compressor operation and provides valid results for future reference.
