Abstract: In this paper, the plate simulation for simulating a distortion flow field is developed to simulate a flow field a large distortion value at the outlet of an inled. Four flow field with large distortion values are successfully simulated by the developed plate simulator. The simulated results show that it can simulate accurately both the distortion contour maps of the steady state total pressures and large distortion values, and that the maximum among four distortion values, DC90, is about -1.118. The distortion value of the flow field simulated can be greatly increased by adding a Small radial plate on the plate simulator while the contour maps of the steady state total pressure is less change. The aerodynamic properties (such as total pressure recovery, tubulence level, distortion contour maps) of the distortion field behind the plate simulator are described.
