Abstract
Based on the RNG k – e turbulence model, numerical simulation was carried out for aerodynamic characteristics of German ICE high-speed railway train under different wind direction angles and different wind angles of attack. In order to verify the accuracy of numerical simulation, the experimental platform of CUMT for the flow field visualization was used to check the result under the same conditions. Further more, the interaction among wind angles of direction, wind angles of attack and pressure coefficient, lift coefficient, overturning moment coefficient were discussed in this paper. The calculation results show that, with the increasing of wind angle of direction and wind angle of attack, the aerodynamic forces and overturning moment of the train increased gradually, which is unfavorable for high-speed railway train.
