In this paper, the effect of activation energy, Soret, and Dufour on non-isothermal heat transfer via the non-linear wall of the steady convective flow of micropolar nanofluid magnetohydrodynamics is investigated. Variations in thermophoresis, Brownian motion, couple stress, and Hall current are also considered. Transformations are used to simplify and then solve the governing equations using the optimal homotopy analysis method and are numerically visualized for results. The behavior was examined and explained in all profile graphs. Tables are presented to illustrate the effect of dimensionless parameters on skin friction coefficients, Nusselt and Sherwood numbers. The concentration reduces via the chemical reaction rate, a temperature relative parameter, and increases with an increase in the activation energy and Soret number. It was found that the local skin-friction coefficient at the generator increases with an increase in the Hall current parameter, solutal Grashof number, and couple stress parameter on the x-axis, the local heat rate decreases through the Dufour number and Brownian motion parameter, and the mass transfer rate increases with an increase in the activation energy parameter and Schmitz and Reynolds numbers.

霍尔MHD发生器系统中Soret，Dufour和活化能对双扩散对流耦合应力微极性纳米流体流动的影响

本文研究了活化能，Soret和Dufour对微极性纳米流体磁流体动力学稳定对流流动的非线性壁传热的影响。还考虑了热泳，布朗运动，耦合应力和霍尔电流的变化。使用最佳同伦分析方法，将变换用于简化然后求解控制方程，并对结果进行数字可视化。在所有配置文件图中检查并解释了该行为。列出表格以说明无量纲参数对皮肤摩擦系数，Nusselt和Sherwood数的影响。浓度通过化学反应速率，温度相对参数而降低，并随着活化能和Soret数的增加而增加。X -轴，局部热速率通过Dufour的数目和布朗运动参数，并与增加的活化能参数和施米茨和雷诺数的传质速率的增加而减小。
