It is pointed out that the ratio of macromixing time to total mixing time increases with the increase in power consumption by calculation. 计算表明,宏观混合时间与整个过程的混合时间的比例,随单位体积功耗的增大而增大。
The mixing time measured by iodine solution fading is analyzed basing on the turbulence theory and micromixing theory. The mathematic model has been developed for macromixing and micromixing in the fading process, and the model parameters for three kinds of impellers are given. 用湍流理论和微观混合理论对碘液退色测混合时间方法进行分析,建立了退色过程中宏观混合与微观混合的数学模型,并给出了三种桨叶的模型参数。
Investigation on MACROMIXING and micromixing of liquid-liquid phase 液液相宏观与微观混合的研究
It is suggested that macromixing and micromixing are considered at the same time in the k ε E model and the predicted data agrees well with experimentally measured data. So the k ε E model established in this paper is reasonable. 模拟结果表明,k-ε-E模型由于同时考虑了宏观混合和微观混合的作用,其预测值和实验测试值吻合较好。
Macromixing and micromixing of liquid-liquid phase is investigated by improved chemical coupling method. The influences of various operation conditions such as stirring speed, feeding speed and position, and impeller type on segregation index investigated. 采用改进的化学偶合法研究液-液相的宏观混合与微观混合,研究了搅拌转速、加料速度与位置等操作条件以及桨型对分隔指数的影响。
