The experiments of reverse flow in a single-stage axial-flow compressor were completed.The parameters

such as velocities

static and total pressure

incidence and deviation

were measured at three sections:the inlet section of rotor

the section between rotor and stator

the outlet of stator.The pressures and temperatures of the flow are measured with a steady acquisition system.The experimental results show that

uniform flow parameters are obtained at the outlet section of stator

but the parameters in the inlet section of rotor vary obviously at the radial direction.The incidences of the reverse flow are very large

so there exists a great loss.Therefore

the temeprature rises as the gas flow through the compressor reversely.
