Pulsatile Analysis of Inlet Pressure Distortion in Turbofan Engine

The distorted flow field is generated by a distortion generator with a moveable sliding board in the experiment.Statistical analysis of pulsatile pressure is presented based on methods of amplitude domain,time domain and frequency domain.The characteristics of pulsatile pressure in inlet distorted flow field are obtained.And the relations of pulsatile pressure and steady total pressure distortion charts and maximum instantaneous pressure distortion charts are also researched.
