文摘In this paper , numerically simulational calculations are made on aerodynamic characteristics for power car of 200km/h EMUs, using Computational Fluid Dy-namics software CFX. After calculation, surface pressure, velocity field distribution as well as aerodynamic resistance are obtained. The results of calculations are com-pared with those of wind tunnel test. Comparison shows good agreement.
