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

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.

文件"Original Model"存储了高速列车原始模型的仿真数据；文件"Noise Reduction Model"存储了采用被动射流（passive jet）后的高速列车仿真数据。该仿真数据文件中的S1为流场仿真数据，S2为声场仿真数据。文件"Origin"为远场气动噪声值的绘图结果。
