Decomposition and reduction of aerodynamic drag of high-speed train

Last updated on 27 November 2013 10:15

During the development of HEMU-430X, extensive aerodynamic study has been performed to assess and reduce the aerodynamic drag of the train. Wind tunnel measurements for the 1/20th scale train model have been performed up to 70m/s freestream wind velocity. Numerical simulation has been conducted and the solutions have been compared...
