The fluid flow with chemical reaction is one of well-known research areas in the field of computational fluid dynamic. It is potentially useful in the modelling of flow on a nuclear reactor. Motivated by the implementation of the flow in the industrial application, the aim of this study is to explore the time-dependent squeeze flow of magnetohydrodynamic Jeffrey fluid over permeable medium in the influences of Soret and Dufour, heat source/sink and chemical reaction. The presence of joule heating, joule dissipation and radiative heat transfer are analyzed. The flow is induced due to compress of two surfaces. Conversion of partial differential equations (PDEs) into ordinary differential equations (ODEs) is accomplished by imposing similarity variables. Then, the governing equations are resolved using Keller-box approach. The present outcomes are compared with previously outcomes in the literature to validate the precision of present outcomes. Both outcomes are shown in close agreement. The tabular and graphical results demonstrate that wall shear stress and velocity profile accelerate with the surfaces moving towards one another. Moreover, the concentration, temperature and velocity profiles decreasing for the increment of Hartmann numbers and Jeffrey fluid parameters. The impacts of heat generation/absorption, joule dissipation and Dufour numbers enhance the heat transfer rate and temperature profile. In contrast, the temperature profile drops and the heat transfer rate boosts when thermal radiation increases. The concentration profile decelerates, and the mass transfer rate elevates with raise in Soret number. Also, the mass transfer rate rises for destructive chemical reaction and contrary result is noted for convective chemical reaction.
带化学反应的流体流动是计算流体动力学领域中著名的研究领域之一。它在核反应堆流动建模中具有潜在的应用价值。受工业应用中流动的启发，本研究旨在探讨磁流体动力学 Jeffrey 流体在渗流介质中的时变挤压流动，考虑 Soret 和 Dufour 效应、热源/汇和化学反应的影响。分析了焦耳加热、焦耳耗散和辐射热传递的存在。流动是由两个表面的压缩引起的。通过施加相似性变量，将偏微分方程 (PDE) 转化为常微分方程 (ODE)。然后，使用 Keller-box 方法求解控制方程。将目前的结果与文献中的先前结果进行比较，以验证目前结果的准确性。两个结果都显示出很好的一致性。表格和图形结果表明，随着表面相互靠近，壁面剪切应力和速度分布加速。此外，随着哈特曼数和 Jeffrey 流体参数的增加，浓度、温度和速度分布都降低。热生成/吸收、焦耳耗散和 Dufour 数的影响增强了传热速率和温度分布。相反，当热辐射增加时，温度分布下降，传热速率增加。浓度分布减速，传质速率随 Soret 数的增加而升高。对于破坏性化学反应，传质速率增加，而对于对流化学反应，则出现相反的结果。
