摘要:
将隧道内流场划分为3个区域,从上到下分别为壁面影响区、车辆影响区及紊流推进区。根据卡门流速分布亏损律,建立了单向连续车流下二维公路隧道紊流方程,引入普朗特掺混长度理论和范德里斯公式,得到了3个区域的二维流速分布公式。以1:10的缩尺比例搭建了隧道通风实验平台,测试了在4种模型车速下隧道中截面的风速,对比验证了二维流速分布公式的准确性。最后基于二维流速分布公式和实验数据,分析了公路隧道中3个分区的风场特性,并给出了隧道平均活塞风速计算公式≈0.486v0-0.116 7(v0为车辆行驶速率)。
Abstract:
For the airflow inside the road tunnel with three divided regions of wall-affected zone,vehicle-affected zone and turbulence zone,two-dimensional turbulence equations of road tunnel under continuous unidirectional traffic were established,according to Carmen velocity defec law.The two-dimensional velocity distribution formulas of the three regions were obtained after rupulangte mixing length theory and van der Rees formula was cited.Experimental platform for road tunnel ventilation was built using 1/10 scale model tunnel and model vehicles.Velocities of 13 points in the middle section of the tunnel were tested on four model vehicle ones.The accuracy of the two-dimensional velocity distribution formula was verified and compared with the test data.Based on the two-dimensional velocity distribution formula and experimental data,the characteristics of the air flow in road tunnel were analyzed and the average piston wind tunnel formula was presented,it is ≈0.486v0-0.116 7(v0 is vechicle speed).
