| 摘 要： | 为了降低高速铁路隧道出口微压波对周围环境的影响,采用了三维粘性、可压缩、不等熵、非定常流的Navier-Stokes方程作为控制方程,空间离散采用了中心有限体积法格式,隧道壁和泄压井壁采用了壁面函数处理。针对高速列车突入带泄压井的隧道进行了数值模拟。计算结果表明,泄压井能有效降低高速铁路隧道出口微压波峰值,而且泄压井高度、隧道长度和列车速度对隧道出口的微压波峰值都有重要影响。 |

| Abstract: | To decrease the influence of high-speed railway tunnel exit micro-pressure wave to sur- rounding environment,this paper used the Navier-Stokes equations described by three-dimensional unsteady viscous compressible non-homentropic flow as the control equations and,a cell-centered finite volume scheme for numerical integration of the Navier-Stokes equations was used for space discretization.In addi- tion,the wells of the tunnel and shaft were described with wall functions to simulate the micro-pressure wave produced by a high-speed train entering a tunnel with a shaft.The calculated result shows that the shaft can sharply decrease the peak of the high-speed railway tunnel exit micro-pressure wave,and the height of the shaft the length of the tunnel the speed of the train play a significant effect on the peak of the micro-pressure wave. |
| Keywords: | shaft high-speed railway tunnel miro-pressure wave finite volume method wall functions |
