With famous flow-field analytic software CFX we also simulated the flow's details in the homogenizers head, and analyzed it's infection to the homogenization process using the simulation results. We also established the dynamic model of the stator-rotor of shear homogenizer system, and analyzed important factors that affect the system's stability with the help of the poincarémaps, axes contrails, phase plane portraits, times-history and amplitude spectrum which were attained by Fortran language and Matlab program.

然后，本文运用商业通用流体动力学分析软件CFX对均质头内部的流场进行了仿真模拟，并与数学模型相结合，探讨了剪切式均质机内部的流场对均质效果的影响，得出提高转速是提高均质机效率的关键，但是转速的提高又直接关系到系统的稳定性，于是紧接着建立了剪切式均质机转子系统的动力学模型，经无量纲化和必要的简化后再运用Fortran语言和Matlab软件对该模型编写相应的程序，得到了庞卡莱图，轴心轨迹图，相图，波形图，频谱图等图谱。
