The numerical simulation of internal flow and overall performance for a 1.5 stage transonic axial flow compressor was conducted by three dimensional viscous flow calculation software Fine/Numeca.The characteristic curves of the transonic axial flow compressor were obtained.The unsteady calculation of compressor internal flow was conducted at the maximum efficiency point and near stall point at two mass flow.The variations of the compressor internal flow were analyzed when the mass flow reduced.
