A model describing the influence of temperature on degree of concentration polarization is proposed. The model is based on the following assumptions: (1) membrane morphology is temperature-independent; (2) transport characteristics of membrane are invariant with coordinate; (3) specific water permeability of the membrane is based on exponential dependence of viscosity vs. temperature; (4) temperature-dependence of membrane rejection is assumed to be linear. Proposed models permit quantitative correlations of longitudinal mass flow and degree of concentration polarization at different operating temperatures. It enables analysis of the influence of temperature, mass flow, bulk concentration, axial velocity, channel geometry, physical properties and membrane rejection on longitudinal distribution of concentration polarization degree. The submitted model does not contain digital integration and can be segmented into optimization algorithms.
提出了一个描述温度对浓差极化程度影响的模型。该模型基于以下假设：（1）膜形态与温度无关；（2）膜的传输特性不随坐标变化；（3）膜的比水渗透率基于粘度与温度的指数关系；（4）假设膜截留率的温度依赖性是线性的。所提出的模型允许对不同操作温度下的纵向质量流和浓差极化程度进行定量关联。它能够分析温度、质量流、本体浓度、轴向速度、通道几何形状、物理性质和膜截留率对浓差极化程度纵向分布的影响。所提交的模型不包含数字积分，可分为优化算法。
