| 摘 要： | 采用滑移边界条件,分析了颗粒群与壁面摩擦力的2个决定因素:摩擦系数和法向压力,提出了摩擦力计算表达式,并应用于模拟干熄炉内焦炭运动的粘性流模型。计算结果表明,滑移边界条件的处理能显著改善干熄炉渐扩段的模拟;干熄炉中下部,壁面摩擦力对近壁处焦炭下降影响显著;文中提出的摩擦力计算方法适用于模拟干熄炉内焦炭下降的粘性流模型。

| Abstract: | By means of slip movement boundary condition, two decisive factors of particle group and wall friction are analyzed: friction factor and normal pressure, the expression for calculating friction is given and is used for simulating viscous flow model for descending of coke in CDQ chamber. The calculated results show that the disposal of slip boundary condition can substantially improve the simulation in expanding section of CDQ chamber; At the lower part of CDQ chamber, the wall friction has obvious influence on coke descending near the wall; the friction calculating method given in the paper is applicable to simulating viscous flow model of coke descending in CDQ chamber. |
