分析了幂律流体在高zeta电位下矩形微通道内电渗流的数学模型。在不考虑德拜-休克尔线性近似的情况下，考虑了双电层（EDL）的电势分布。通过数值解分析了流体的流动特性。进行参数研究以评估不同流动行为指数（n）值的剪切应力、粘度和体积流率的变化。计算结果被用来解释使用一个相对假塑性流体内的微通道，以获得更高的体积流量的可能性。(C)2010年爱思唯尔BM。All rights reserved.
In this paper, a mathematical model for electroosmotic flow of power-law fluids in a rectangular microchannel at high zeta potential is analyzed. The electric double layer (EDL) potential distribution is considered without Debye Huckel linear approximation. Numerical solution is obtained to analyze the fluid flow behavior. Parametric studies are conducted to assess the variation of shear stress, viscosity and volumetric flow rates of various values of flow behavior index (n). Computed results are used to explicate the possibility of using a relatively pseudoplastic fluid inside microchannel to obtain higher volumetric flow rates. (C) 2010 Elsevier BM. All rights reserved.
