Abstract

In this manuscript, the impact of Soret and Dufour numbers on magnetohydrodynamic (MHD) flow for Silver (Ag) and Copper (Cu) water-based nanofluids past a moving plate over a porous medium are investigated numerically. The influences of heat sources and chemical reactions are also considered, as their applications are prevalent in several industries. The flow's constituents' governing equations are coupled with Partial differential equations (PDEs) that are converted into a dimensionless form using appropriate flow parameters. Subsequently, the finite-difference technique is used to resolve the resulting equations. The varied effects of flow parameters on the momentum, temperature, and concentration boundary layers are investigated using various graphs. The results presented in terms of non-dimensional parameters like shear stress factor, Sherwood number, and Nusselt number of fluids are tabulated for the nanofluids Ag-water and Cu-water. It is found that the augmented values of Dufour and Soret numbers enhance the fluid velocity. However, the species concentration decreases in the existence of Dufour and chemical reaction effects.

双扩散、化学反应和热源对铜和银水基纳米流体在移动的垂直多孔板上磁流体动力学流动的影响

在本文中，数值研究了Soret和Dufour数对银（Ag）和铜（Cu）水基纳米流体通过多孔介质上移动板的磁流体动力学（MHD）流动的影响。热源和化学反应的影响也被考虑在内，因为它们的应用在几个行业中很普遍。流量成分的控制方程与偏微分方程（PDE）相耦合，偏微分方程使用适当的流量参数转换为无量纲形式。随后，使用有限差分技术来求解所得到的方程。使用各种图表研究了流动参数对动量、温度和浓度边界层的不同影响。表中列出了纳米流体Ag水和Cu水的无量纲参数，如剪切应力因子、流体的Sherwood数和Nusselt数。研究发现，Dufour数和Soret数的增广值提高了流体的速度。然而，物种浓度的降低是由于Dufour的存在和化学反应的影响。
