Abstract

For the general case of high-speed trains passing a tunnel under crosswinds, considering the unsteady compressible turbulence characteristics of the flow, a 3D numerical model including train-tunnel-crosswind was established to and study the aerodynamic pressure change laws and slipstream characteristics under the conditions of crosswinds and without crosswinds comparatively. The accuracy of the numerical method was validated by the full-scale experiment. The main conclusions can be summarized as follow: Compared with the condition of without crosswind, the transient pressure and slipstream near the tunnel entrance change significantly when the train enters under crosswind. Before the full entry of the tail car, the influence of crosswind on the aerodynamic pressure at the leeward side is greater than that on the windward side, and the influence of the head car on the aerodynamic pressure at the tunnel entrance is the most significant. The influence of crosswind on aerodynamic pressure and gust in tunnel is limited. When the crosswind speed is 24.4 m / s, the distance affected in the tunnel is 50 m. When the head car enters, the crosswind has a great influence on the train wind on the leeward side of the train, while the influence of crosswind on the windward side of the train is more serious when the tail car enters completely. The crosswind effect is the fundamental reason for the large fluctuation of aerodynamic pressure and air velocity.
