摘要
分析了工作面流场中粉尘颗粒的受力状态,采用Lagrange方法研究了单个尘粒在风流中的运动,导出了描述颗粒运动的微分方程(组),得到了尘粒在铅垂和水平两个方向的运动特征及粉尘颗粒的运动轨迹。这种研究尘粒“宏观” 运动的方法,将为粉尘的防治工作提供有益的技术参数。
The paper analyzes the forces acting on dust particle.The dominant forces are taken into a ccount.In Lagrange Coordinate,a simple dust particle movement is studied.Differential equations and integral equations are derived.Movement characteristics on two basic directions,i,e.vertical and horizontal directions are obtained.The model is applicable for both horizontal and inclined airway.
