Numerical Simulation on Effect of Obstructing Airflow by Different Outlet Parameters of Mine Air Curtain Ling Zhao1,2,a ,Zhongan Jiang1 1 Civil and Environmental Engineering School, University of Science and Technology Beijing, Beijing, China 2 Resource and Environmental Engineering School, Jiangxi University of Science and Technology, Ganzhou, Jiangxi, China a jxlgdxzl@163.com Keywords: mine air curtain; outlet parameters; numerical simulation; the amount of air leakage; obstructing airflow capability Abstract.
According to characteristics of air curtain obstructing airflow in mine tunnel, utilized turbulent flow dynamic viscosity method, and three-dimensional steady-state incompressible Navier-Stokes equations of computational fluid mechanics, the simulation of flow field in mine tunnel was made by changing outlet parameters of air curtain.
When the parameters are the same, the obstructing airflow capability of acyclic air curtain is better than that of circular air curtain.The result of simulation analysis of mine air curtain can be used as the basis for optimized design.
In the simulation, the outlet air volume was 12.87 m3/s, the outlet angle was 30°, the relation curves about the amount of air leakage and outlet width were gained and were shown in Fig.4.
