以地铁车站和区间隧道通风空调与防排烟系统设计对空气流动数值模拟的需求为目标,指出地铁工程空气流动数值模拟存在的问题,提出利用三维n连体模型空气流动数值模拟对一维网络模型进行校验与修正的方法,工程案例计算结果表明,三维n连体模型兼顾了三维模拟的精确性与一维模拟的网络化与高效性,能够适应地铁工程设计阶段的要求,可用于校验与修正一维网络模型。
Taking the demand of air flow numerical simulation for metro station and tunnel tunnel ventilation and air conditioning and smoke exhaust system design as objective, the problems in numerical simulation of subway air flow are pointed out. The numerical simulation of air flow in subway station, Model verification and correction methods, engineering case calculation results show that the three-dimensional n-piece model takes into account the accuracy of three-dimensional simulation and one-dimensional simulation of the network and high efficiency, to meet the requirements of the subway project design phase can be used for school Inspection and revision of one-dimensional network model.
