Abstract
Three-dimensional unsteady viscous numerical simulation was conducted on an axial-radial combined compressor to study the interaction characteristic of wake/potential and downstream potential effects on the mid stator vane. The axial rotor/stator vane, axial rotor/impeller and stator vane/impeller interaction effects on the impeller inlet angle were also investigated by using the effect factor split of the combined compressor unsteady flow. The results show that upstream wake and downstream potential lead to reinforce/suppress effect while coupling in the mid vane passage. Due to the different phases of axial rotor/stator vane, axial rotor/impeller and stator vane/impeller interaction, work fluid at impeller inlet encounters distortion, which directly affects the amplitude of inlet angle.
