摘要:
为建立相对精确的磷酸陈化槽的固液两相混合过程数值模拟的方法,指导此类搅拌器的设计并优选搅拌结构,使用计算流体力学软件FLUENT对磷酸陈化槽内的固体颗粒与液体的搅拌混合过程进行了三维数值模拟,根据Zwietering的关联式得出搅拌临界转速,利用多相流模型中的欧拉模型来解决悬浮液中的固体颗粒沉降问题,采用多重参考系法(MRF),选用标准κ-ε湍流模式,模拟出平底磷酸陈化槽中液体的流动情况和体积分数的分布、分析垂直面内和水平面内液相的流场分布规律、固相颗粒体积分数特点,并探讨了产生这种情况的原因.模拟结果表明PBT搅拌桨所产生的轴向流流型比较适合固液搅拌操作.
Abstract:
To establish a possible method for phosphate aging tank solidliquid mixing process simulation, and to optimize the solidliquid mixers, threedimensional numerical simulation of phosphate aging tank solidliquid mixing process was carried out by using computational fluid dynamics software FLUENT. The Zwietering correlate equation was used to calculate the critical speed of rotation, The multireference frame(MRF) and standard κ-εturbulent model were used to describe the rotational turbulent flow in stirred tank, and the EulerEuler model was used to analyze the solidliquid twophase flow. Finally, the flow situation and the density distribution of the phosphate aging tank were simulated, the fluid distribution laws of the liquid and the density characteristics of the solid particles in vertical and horizontal plains were analyzed. The result of the simulation shows that the axial flow pattern made by PBT airfoil impeller type agitator is suitable for solidfluid mixing.
