Based on the effect of movable flat baffles plenum volume on inlet pressure distortion flow field of engine

the destabilization characteristic of the movable flat baffles plenum volume on small flux tube engine air flow field was obtained. Through the process of problem discovery

analysis

numerical simulation

improved design

and test verification

the movable flat baffles plenum volume was proved in reducing the distortion intensity of inlet pressure flow field

and the engine of less than 200mm diameter flux tube was covered within the range of effect. In order to avoid destabilization to the inlet air flow field of the movable flat baffles plenum volume

corresponding measures should be taken to reduce the volume in the design of the pressure distortion device.
