摘要
分析了综采工作面流场及粉尘分布的特点 ,视工作面含尘风流为气 粒两相流 ,建立了描述综采工作面风流中粉尘运动和浓度分布的数学模型。采用计算流体力学的有限容积法求解 。
Based on underground dust measurement, the dust-laden airflow in long wall coal face is taken as 3-dimensional steady turbulent gas-particulate flow. A mathematical model is set up and the differential equation is solved by numerical solution of finite volume method. A 3D/2P computer program is developed successfully. An example of dust distribution is studied, which concludes that the dust should be controlled at the dust source. The computer program can be used to evaluate the dust control measures.
