| 摘 要： | 井下作业人员利用带条缝风口安全帽的条缝射流来阻挡粉尘侵袭人的面部,这属于气一固两相流的范畴.本文采用Realizable湍流模型来求解条缝射流气流流场中的速度场,在此基础上,建立气一固两相流动的数学模型来研究采煤区粉尘浓度的分布规律.文章对四种不同风口宽度下的条缝射流进行数值模拟,通过对比分析,得到有利于粉尘隔离的条缝...

| Abstract: | It is belongs to gas-solid two-phase flow that coal miners use crack jet in order to stop the dust blow into people's faces.This paper used the Realizable turbulence model to solve the velocity field in the crack jet,based on this,established gas-solid two-phase flow mathematical model to study the distribution rule of dust concentration on coal face.Based on the numerical simulation of four different crack jet width conditions,through comparison and analysis,we found that 6 millimeter's slot diffuser is co... |
