Abstract
Based on 3D steady and incompressible N-S equation and k-e turbulent model,the aerodynamic performance of trains running under different situations was simulated by finite volume method.The influence of locomotive speed,wind speed and embankment height on the aerodynamic performance of high-speed locomotive was analyzed.The results show that the aerodynamic forces increase with the increase of embankment height,train speed,crosswind speed and crosswind angle.Because the range of train speed in this paper is small,its influence of high-speed locomotive on the aerodynamic performance is less than the other factors.
