Abstract In this study, the behavior of a microchannel flow is examined. The fluid is considered to be a nanofluid, which moves between two parallel flat plates in the presence of an electrical double layer. The Buongiorno nanofluid is considered with body force. In this study, the unphysical supposition presented in the preceding work to the discontinuity of the flow fled where the electrostatic potential in the central of the canal must be equal to zero is removed. The incorrect supposition that the pressure constant is preserved, which is considered a known form, is corrected. The current fresh model equation is modified by using dimensionless parameters to convert partial differential equations into ordinary differential equations. The transformed nonlinear equations are solved by the homotopy analysis method. The physical parameters, magnetic parameters, Eckert number, Lewis number, Brownian motion parameters, thermophoresis parameters, and Prandtl number are analyzed. The influence of both the viscous and Joule dissipation in the presence of magnetohydrodynamic effect is examined.

界面电动力学对具有布朗运动和热泳效应的可渗透微通道中 MHD 辐射纳米流体流动的影响

摘要 在这项研究中，研究了微通道流动的行为。该流体被认为是纳米流体，它在存在双电层的情况下在两个平行平板之间移动。Buongiorno 纳米流体被认为具有体力。在这项研究中，去除了先前工作中提出的非物理假设，即在运河中心的静电势必须为零的情况下，流动的不连续性被消除了。修正了压力常数保持不变的错误假设，这被认为是已知形式。通过使用无量纲参数，将偏微分方程转化为常微分方程，对当前的新模型方程进行修正。变换后的非线性方程组采用同伦分析法求解。物理参数，分析了磁参数、埃克特数、路易斯数、布朗运动参数、热泳参数和普朗特数。检查了存在磁流体动力学效应时粘性耗散和焦耳耗散的影响。
