This paper reports the mass and energy transmission characteristics of an electrically conducting mixed convective nanofluid flow past a stretching Riga plate. An additional effect of viscous dissipation, Arrhenius activation energy and heat source is also studied. The energy and mass transmissions are evaluated by a zero-mass flux of nanoparticle and convective boundary conditions. Buongiorno’s relations are proposed for the Brownian motion and thermophoretic diffusion. The similarity substitutions are employed to derive the non-dimensional set of modeled equations. The obtained set of equations is numerically processed via parametric continuation method (PCM). Several flow factors affecting the velocity, energy, and mass distributions are graphically discussed. It has been perceived that the fluid velocity field declines with the influence of velocity power index (m), while improves with the upshot of modified Hartmann number (Q). The effect of Schmidt number and chemical reaction diminishes the concentration profile $\phi (\eta )$. Furthermore, the energy curve enhances with the effect of thermophoresis factor, Biot and Eckert number.

本文报告了导电混合对流纳米流体流过拉伸里加板的质量和能量传输特性。还研究了粘性耗散、阿累尼乌斯活化能和热源的附加效应。通过纳米颗粒的零质量通量和对流边界条件来评估能量和质量传输。针对布朗运动和热泳扩散提出了 Buongiorno 关系式。采用相似替换来导出无量纲建模方程组。通过参数连续法（PCM）对获得的方程组进行数值处理。以图形方式讨论了影响速度、能量和质量分布的几个流动因素。可以看出，流体速度场随着速度功率指数（m）的影响而下降，而随着修正哈特曼数（Q）的影响而改善。施密特数和化学反应的影响减小了浓度分布$\phi （\eta ）$。此外，能量曲线随着热泳因子、毕奥数和埃克特数的影响而增强。
