摘要
根据雾滴在横向风流中的受力理论,建立了单个雾滴在巷道中的运动方程,采用Matlab对方程进行求解,得出不同粒径大小的细水雾在巷道中的运动轨迹。搭建了模拟巷道实验台,在此实验台的基础上进行了细水雾扩散特性实验,将实验结果得出的细水雾扩散距离实验值与理论值相比较,验证了细水雾雾滴在模拟巷道中运动轨迹模型和求解的正确性。
According to the force theory of fog droplet in transverse airflow, the motion equation of a single droplet in the tunnel is built and solved by using Matlab, the motion trajectory of water mist with different sizes of droplets in the tunnel is also obtained. Based on the simulated test bench, the movement and diffusion experiment of water mist is conducted. Comparing the experimental value with the theoretical value of diffusion distance of water mist, the correctness of trajectory model of water mist in simulated roadway and solution is verified.
