Purpose

This paper aims to investigate the effect of Powell–Eyring fluid induced by a stretched sheet. Heat and mass transfer under the influence of magnetic dipole over a stretching sheet are taken into account.

Design/methodology/approach

Nonlinear coupled governing equations are solved using the optimal homotopy asymptotic technique, and a computer software package BVPh 2.0 is used for numerical computations.

Findings

Impact of significant quantities is graphically examined. It is seen that the heat transfer deceases for higher values of viscous dissipation parameter, radiation parameter, Dufour number, whereas it increases for bigger values of Prandtl number. The numerical results have been validated through comparison with existing literature as a special case of proposed model and perceived that the Soret number has reining role to increase the rate of heat transfer.

Originality/value

To the best of the authors’ knowledge, this study is reported for the first time.

磁偶极子的Dufour，Soret和辐射效应对拉伸片上Powell-Eyring流体的流动

目的

本文旨在研究拉伸片材诱导的鲍威尔-艾林（Powell-Eyring）液的作用。考虑到在拉伸片上在磁偶极子的影响下的热和质量传递。

设计/方法/方法

使用最佳同伦渐近技术求解非线性耦合控制方程，并使用计算机软件包BVPh 2.0进行数值计算。

发现

以图形方式检查了大量的影响。可以看出，对于较高的粘性耗散参数，辐射参数，杜福尔数，传热会降低，而对于较大的普朗特数，传热会增加。通过与现有文献进行比较，将数值结果作为所提出模型的特例进行了验证，并认为索雷特数对提高传热速率具有控制作用。

创意/价值

据作者所知，该研究是首次报道。
