Study on the influence of passive jet on the aerodynamic acoustic characteristics of high-speed train pantographs

Description

The file "Original Model" contains simulation data of the original model of the high-speed train, the file "Noise Reduction Model" contains simulation data of the high-speed train after applying passive jet. S1 in the simulation data file is the flow field simulation data, and s2 is the sound field simulation data. the file "Origin" is a plot of far-field aerodynamic noise values.
