摘要

利用Fluent动网格技术，对高速列车通过圆形全封闭声屏障产生的压力波和出口微气压波开展数值模拟研究。研究结果表明：列车通过圆形全封闭声屏障时，声屏障壁面风压变化过程与压缩波和膨胀波的产生、传播及反射有关，压缩波传播到壁面测点时压力上升，膨胀波传播至壁面测点时，压力下降；在声屏障横截面上，靠近列车的测点压力极值大于远离列车的测点压力极值，最大差异量达到28%；声屏障壁面压力变化幅值、车头鼻尖压力最大值与车速的二次方近似呈正比关系；与隧道结构类似，列车以较高的速度通过声屏障时，将在声屏障出口产生微气压波，微气压波的极值随着到出口的距离增大而迅速降低，并与列车速度的三次方近似呈正比关系。

Abstract

The pressure waves and micro pressure waves generated by high-speed trains passing through a circular enclosed sound barrier are numerically simulated with a moving-grid technique. Results show that: when a train passes a circular enclosed sound barrier

the pressure variations on the wall of the sound barrier are related to the generation

propagation

and reflection of compression and expansion waves. The pressure amplitude increases when the compression waves propagate towards measuring points on the wall

while the opposite is true for expansion waves. In the cross section of the sound barrier

pressure extrema at the measuring points near the train are larger than those at the measuring points far from the train

with a maximum difference about 28%. The difference of pressure amplitudes on the wall of the sound barrier and the maximum pressure on the nose tip of train heads are approximately proportional to the square of train speeds. When a train passes the sound barrier at a higher speed

micro-pressure waves will be generated at the exit of the sound barrier

whose extrema decreases rapidly as a function of the distance to the exit. The extreme values of micro-pressure waves are approximately proportional to the cube of train speeds.
