摘　　要：掌握泥浆搅拌装置设计的关键技术,依赖于泥浆搅拌过程的研究.在对两相流有限元计算方法和模型展开讨论的基础上,基于欧拉-欧拉方法的Eulerian模型,利用Fluent流体仿真软件,实现了汽车轮毂轴承性能试验中泥浆搅拌过程的数值模拟.通过模拟得到的泥浆固相颗粒分布云图,研究搅拌槽的浓度分布和均匀性.提出了泥浆搅拌装置功能设计的基本要求,研究了泥浆固相颗粒在搅拌槽底部的完全离底悬浮问题和取浆口的设置问题.相关技术已用于指导泥浆搅拌装置的设计.The research of mud mixing process is the key technology of mud mixing device design.Through the study of Two-Phase Flow finite element method and model,in the property test of wheel hub bearing,the numerical simulation of mud mixing process is realized by using fluent software based on Eulerian model and Euler-Euler method.The concentration distribution and uniformity of mixing tank are studied,by simulating the contours of mud particles distribution.Furthermore,the basic requirements of functional design in the mud mixing device are put forward,and the problems of complete suspension and the setting of mud particles outlet in the mixing tank are studied.Related techniques have been used to guide the design of mud mixing device.
