摘要

研究了Soret和Dufour对具有化学反应的垂直多孔板上非定常MHD对流传输的影响。在有限差分法的帮助下，应用相似度分析对形成非线性控制方程的模型进行了变换。流体特性如速度、浓度和温度的数值分辨率用图形解释。本研究还给出了传质率、传热率和局部表面摩擦系数，并以表格形式进行了解释。结果表明，流体运动和温度的提高对Dofour效应的增长值有促进作用。此外，流体的速度和浓度也会随着Soret效应的增加而提高。随着Soret数(0.5-2.0)的增加，局部皮肤摩擦提高约66%，质量传播率降低约247%。

Effects of Soret and Dufour on Unsteady Magneto-Convective Transport through a Vertical Perforated Sheet with Chemical Reaction

An investigation of the effects of Soret and Dufour on an unsteady MHD convective transmission over a vertical porous sheet with chemical reaction was introduced throughout this study. The model that formed nonlinear governing equations is transformed by applying the similarity analysis with the help of the finite difference method. The numerical resolutions of the fluid characteristics like velocity, concentration, and temperature are explained graphically. This research also presented the mass transmission rate, heat transmission rate, and the local skin friction coefficient, which are explained in tabular form. The results give the fluid motion and temperature improvement for growing values of the Dofour effect. Also, the fluid velocity and concentration improve for elevated amounts of the Soret effect. The local skin friction improves by around 66% whereas the mass transmission rate lessens by around 247% with the growing Soret number (0.5–2.0).
