摘　　要：介绍了国内外隧道通风系统的最新研究进展.研究了两种分析隧道通风活塞效应的数值模拟方法:动网格法和动量源项法.动网格法通过模拟车辆的真实运动,可以给出隧道内详细的三维空间局部参数的变化趋势,但该方法模拟耗时巨大,效率较低.动量源项法通过添加一个动量源来实现车辆移动,该方法可避免消耗大量的计算资源和时间,从而大大提高模拟效率.The review of tunnel ventilation systems was presented and the latest related researches in the countny and abroad were introduced. Two numerical simulation methods were proposed to analyze the piston effect in the tunnel：dynamic mesh and momentum source method. The dynamic mesh method can reveal the real motion of vehicles and provide a detailed information of local parameter changes in 3- D space, however, much time should be taken for simulation and the efficiency is low. The momentum source method can achieve the vehicle motion by adding a momentum source. The latter method can avoid the large consumption of computing sources and time and can improve the simulation efficiency greatly.
