摘 要:利用数值仿真分析了高长径比容器搅拌釜的流固混合过程。分别采用标准壁面函数和增强壁面函数进行数值仿真,并比较两种壁面条件下的仿真结果。最后,基于铁磁性颗粒电感跟踪装置获取了实际颗粒流固混合曲线。实验结果表明,基于增强壁面函数的颗粒混合数值仿真结果具有更好的准确性。Numerical simulation is used to analyze the fluid-solid mixing process in a stirred kettle with a high aspect ratio vessel.Numerical simulations were carried out using standard wall function and enhanced wall function respectively,and the simulation results under the two wall conditions were compared.Finally,the actual particle flow-solid mixing curves were obtained based on the inductive tracking device for ferromagnetic particles.The experimental results show that the numerical simulation results of particle mixing based on the enhanced wall function have better accuracy.
