摘要
本文通过对微元控制体的研究,建立了超滤数学模型,揭示了溶质扩散和料液流动的冲刷作用对透过速率的联立效应。文章分析了料液的压力,温度、流速和浓度与透过速率之间的关系,并得到了试验验证。
In the paper a mathematical model of permeation flux is developed witha micro-control element.The model describes that solute diffusion and brushaction of solution flow are a combinative effect on the permeation flux.Whereby analyses the relation between permeation flux and pressure,tempe-rature,bulk velocity or concentration of treated solution.Then tests andverifies the model valid with experiment results.
