- Abstract:
- According to the three-dimensional incompressible Navier-Stokes equations and the standard turbu-lence model, the 100 double-line tunnel cross-section which is generally used in high-speed railway of China isstudied,this paper has made a thorough study on the variation rules and distribution characteristics of trainwind,and has calculated the maximum wind speed at different positions on the two evacuation passageways,atthe same time the influence that train wind on personnel safety is further discussed.The results show that:Train wind is complex three-dimensional flow which is changed with time and space,person should avoid ac-tivities at dangerous time,personnel safety may be threatened by train wind on two train driving conditions:one is that a single train runs through tunnel normally while the other is that another train runs beside a trainparked in the tunnel.Corresponding measures should be taken to avoid accidents.
