The effect of relative depth of flat baffle on distortion descriptors characteristics, distortion sensitivity, and pressure field distribution of the three-stage fan was experimentally studied. The results show that the pressure distortion sensitivities increase first and then reduce with increasing of the ratio of steady-state distortion descriptor and time-variant distortion descriptor.
