摘　　要：该文结合济南市某GIL地下管廊的工程实例进行数值模拟,利用ANSYS FLUENT软件研究压力进风、机械排风通风方式下,不同进风温度及同时工作电缆数量对GIL管廊温度场、速度场的影响,并依据模拟结果校核工程设计合理性及提出建议。通过数值模拟分析发现,管廊内空气温度受进风温度影响很大,在工程设计时要考虑夏季室外极端温度的影响。此外,当进风温度较低时,可适当关闭风机,以达到减小风量降低能耗的目的。In this paper,the numerical simulation of an underground GIL pipe corridor in Jinan is carried out,and the effects of different inlet air temperature and the number of simultaneous working cables on the temperature field and velocity field of GIL pipe corridor under pressure air intake and mechanical exhaust ventilation are studied by using ANSYS FLUENT software,and the rationality of engineering design is checked and suggestions are put forward according to the simulation results.Through the numerical simulation analysis,it is found that the air temperature in the pipe corridor is greatly affected by the inlet air temperature,and the extreme outdoor temperature in summer should be considered in the engineering design.In addition,when the inlet air temperature is low,the fan can be turned off properly to achieve the purpose of reducing air volume and energy consumption.
