Abstract This study reveals the characteristics of chemical reaction on Marangoni mixed convective stream towards a penetrable Riga surface. The heat and mass phenomena are analysed within the sight of Dufour and Soret impacts. The administering partial differential equations system is converted into three nonlinear ordinary differential equations utilizing appropriately adjusted transformations. The resultant system of highly nonlinear equations is analytically solved by invoking the homotopy analysis method. Thereafter, the convergence of series solutions is discussed. The impact of appropriate parameters on various flow fields is thoroughly explained with the help of graphs and tables. The wall drag coefficient and relevant flux rates are arranged and discussed for dimensionless parameters. The outcomes show that the stronger Dufour effect of liquid causes a notable incremental variation in heat and mass flux, whereas an opposite trend is noted in the heat flux rate for the Soret effect. However, the mass flux is still found increasing for the stronger Soret effect.

热溶的 Marangoni 对流流向可渗透的里加表面

摘要 本研究揭示了 Marangoni 混合对流流向可穿透的里加表面的化学反应特征。在 Dufour 和 Soret 撞击的视野内分析热和质量现象。使用适当调整的变换将管理偏微分方程系统转换为三个非线性常微分方程。通过调用同伦分析方法对高度非线性方程的合成系统进行解析求解。此后，讨论级数解的收敛性。在图表的帮助下，适当的参数对各种流场的影响得到了彻底的解释。壁阻力系数和相关的通量率被安排和讨论为无量纲参数。结果表明，液体更强的杜福尔效应会导致热量和质量通量的显着增量变化，而索雷特效应的热通量率则出现相反的趋势。然而，仍然发现质量通量因更强的索雷特效应而增加。
