| Abstract |
| This paper gives details of the simulation model including method, flow field, corresponding boundary conditions, geometry, and computational mesh. It then shows the train's aerodynamic flow and loads with a range of variable operating speeds and incoming wind speeds. The aerodynamic interaction between a moving train and the transverse wind is expressed in terms of the flow features around the train, variable yaw angles, and the effect of the moving train on the aerodynamic forces of the train including lateral force, lift force, and rolling moment. This work contains different cases for three basic factors, namely: wind speed, train speed, and yaw angle. Firstly, the train speed is 100 km/h, with a wind speed of 12 m/s, and wind angles of 0, 30, 60, and 90 degrees. Secondly, the train speed is 300 km/h, with a wind speed of 15 m/s, and wind angles of 0, 30, 60, and 9 |
