Influence of air chamber parameters in high-speed railway tunnel on aerodynamic effect of train surface
应用三维、可压缩、非定常Navier-Stokes方程和有限体积法,以单线隧道人行通道下方布置单个气室为例,分析隧道内气室参数对列车表面气动压力和横向力的影响.研究结果表明:隧道中加设气室后列车表面压力峰值增大,且当气室位于隧道前部、气室纵向长度较长、气室入口面积较大时,列车表面压力峰值增大更明显;当隧道长156 m、气室位于隧道前部、气室长度L为50 m、气室入口面积A为1.2 m2、车速为400 km/h时,列车表面瞬变压力的正负峰值分别比无…查看全部>>
Using the three-dimensional,compressible,unsteady Navier-Stokes equations and the finite volume method,the effects of air chamber parameters in a single-line tunnel pedestrian passageway on the aerodynamic pressure and lateral forces on the surface of train were studied.The results indicate that the peak surface pressure of the train increases when air chambers are installed in the tunnel.This effect is more pronounced when the air chamber is located at the …查看全部>>
