本文研究了纳米流体在具有壁面特性的通道中的磁流体动力学（MHD）蠕动传输。讨论了存在粘性耗散、局部滑移和焦耳热效应时的流动分析。数学模型还包括布朗运动和热泳的显著特征。给出了解析解和数值解。两种解决方案的比较结果显示出很好的一致性。重点关注布朗运动参数、热泳参数、哈特曼数。埃克特数和普兰德尔数。研究了各种参数对表面摩擦系数、努塞尔数和舍伍德数的影响。发现温度和纳米颗粒浓度随布朗运动和电泳参数的增加而增加。(C) 2015 Elsevier B.V.版权所有
This paper is devoted to the magnetohydrodynamic (MHD) peristaltic transport of nanotluid in a channel with wall properties. Flow analysis is addressed in the presence of viscous dissipation, partial slip and Joule heating effects. Mathematical modelling also includes the salient features of Brownian motion and thermophoresis. Both analytic and numerical solutions are provided. Comparison between the solutions is shown in a very good agreement. Attention is focused to the Brownian motion parameter, thermophoresis parameter, Hartman number. Eckert number and Prandll number. Influences of various parameters on skin friction coefficient, Nusselt and Sherwood numbers are also investigated. It is found that both the temperature and nanoparticles concentration are increasing functions of Brownian motion and Lhermophoresis parameters. (C) 2015 Elsevier B.V. All rights reserved.
