摘要
为了解决城市单舱综合管廊布置对最优通风量的影响问题,以增强城市单舱综合管廊的通风效果为目的,提出了城市单舱综合管廊最优通风量数值模拟研究。在初始化数值模拟软件的基础上,利用室外通风设计参数,设置了综7合管廊风口的边界条件,结合墙面及近地面边界条件和其他边界条件的设定,完成最优通风量数值模拟边界条件的设置;通过模拟城市单舱综合管廊的设计图,计算了消除余热和排除污染物气体放散量的最优通风量,采用全面通风的方式,计算了城市单舱综合管廊的最优通风量;最后结合综合管廊最优通风量数值模拟流程,实现了城市单舱综合管廊最优通风量的数值模拟。实验结果表明,提出的这种数值模拟方法具有更好的通风效果,利于污染物气体排放,可以一定程度确保施工人员的安全,可以广泛应用到实际生活中。
In order to solve the problem of the influence of the optimal ventilation volume of the layout of the urban single cabin comprehensive pipe gallery,and to enhance the ventilation effect of the urban single cabin comprehensive pipe gallery,the numerical simulation of the optimal ventilation volume of the urban single cabin comprehensive pipe gallery is proposed.Based on the initialization of the numerical simulation software,the boundary conditions of the tuyere of the comprehensive pipe gallery are set by using the design parameters of the outdoor ventilation,and the boundary conditions of the optimal ventilation volume numerical simulation are set by combining the boundary conditions of the wall and near ground and other boundary conditions.By simulating the design drawing of the urban single cabin comprehensive pipe gallery,the waste heat removal and pollutant removal gas emission are calculated.The optimal ventilation volume of the bulk volume is calculated by the way of overall ventilation.Finally,the optimal ventilation volume of the urban single cabin comprehensive pipe gallery is simulated by combining the numerical simulation processes of the optimal ventilation volume of the comprehensive pipe gallery.The experimental results show that the numerical simulation method proposed in this paper has better ventilation effect,is conducive to the emission of pollutants,can ensure the safety of construction personnel to a certain extent,and can be widely used in real life.
