The nonlinear acoustics solver(NLAS) approach is adopted to study the aerodynamic noise in the near field of the CRH3 high speed train.The method validation is conducted through a two-dimensional backward step case,which shows excellent agreement with experimental results.With the help of acoustic surface around the noise sources,far field aerodynamic noise study is carried out by solving the Ffowcs-Williams/Hawking(FW-H) equation.The aerodynamic noise study on CRH3 high speed trains with a speed of 300 km/...
