摘要
为了深入研究煤矿井下粉尘粒子运动轨迹特征,本文采用离散相数学模型,对粉尘二次飞扬情况进行数值模拟,得到粒子在不同风速下的飞扬情况,以及不同粒径粒子的二次飞扬的起风速度。针对粉尘的二次飞扬问题,本文从数值模拟角度描述了煤矿井下粒子运动的数学模型,从理论层次分析了粒子的动力学运动特征。
For the further study on motion trajectory characteristics of dust particle underground, discrete phase model was used to simulate dust secondary flying. The particles＇ flying situation under different wind speed and the wind speed of different sized particle＇ s secondary flying were obtained. The mathematical model of particle movement in coal mine was described from the view of numerical simulation, and the dynamic char- acteristics of the particles was analyzed in this paper.
