为了研究矿井巷道内活塞风动力效应的影响因素及其影响作用,采用标准k-ε湍流模型对矿井巷道内矿车运动时的气流状态进行数值模拟,得到不同条件下矿车运行时巷道内风流速度场和压力场分布特征和变化规律。
In order to study the influencing factors of piston wind dynamic effect in mine roadway and its effect, the standard k-ε turbulence model is used to simulate the state of gas flow during the movement of mine roadway in mine roadway, and the airflow in the mine roadway under different conditions Distribution characteristics and variation of velocity and pressure fields.
