摘要
以内蒙古包头市某综合管廊为研究对象,通过实验与计算流体动力学(CFD)数值模拟相结合的方法研究了在不同通风方式下管廊热力舱内不同管径的热力管道所对应的最佳通风区。结果表明:两种通风方式通风区的长度随着热力管道管径的增加而增加,自然通风、机械排风通风方式下管径为300、400、500、600 mm时最优通风区分别为160、166、178、200 m时可满足巡视人员舒适度要求;在机械送风、机械排风通风方式下,管径为300、400、500、600 mm时最优通风区分别为360、370、385、400 m时即满足要求。该研究对综合管廊实际通风设计有一定指导意义。
A utility tunnel in Baotou City,Inner Mongolia was taken as the research object.The optimum ventilation area corresponding to different pipe diameters in the thermal cabin of the comprehensive utility tunnel under different ventilation modes was studied by combining experiment with CFD numerical simulation.The results show that the length of ventilation area of two ventilation modes increases with the increase of pipe diameter of thermal pipeline.Under natural ventilation and mechanical ventilation modes,the optimum ventilation areas of pipe diameters of DN300 mm,DN400 mm,DN500 mm and DN600 mm are 160,166,178 and 200 m respectively,which can meet the comfort requirements of inspectors.Under the ventilation mode,the optimum ventilation areas of pipe diameters of DN300 mm,DN400 mm,DN500 mm and DN600 mm are 360,370,385 and 400 m respectively,which meet the requirements.The research has certain guiding significance for the actual ventilation design of the utility tunnel.
