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 the droplet in the lateral wind flow, the motion equation of a single droplet in the roadway is established. The equations of the solution are solved by Matlab, and the movement trajectories of the water mist with different particle sizes in the roadway are obtained. Based on the experimental bench, experiments on the diffusion characteristics of water mist were carried out. The experimental results show that the experimental results of the water mist diffusion distance are in agreement with the theoretical values. Simulating the trajectory model in the roadway and the correctness of the solution.
