摘要

非牛顿流体在传热传质流动、金属板的冷却运动、海洋学、生物流体、熔体旋转、涂层热交换器专业知识和中断等领域具有广泛的应用。鉴于这些应用,本文研究了流体磁非牛顿麦克斯韦流体在可渗透介质上的平板流动的数值模拟。讨论了Soret, Dufour和辐射效应。利用相似性变量将非线性偏微分方程转化为非线性偏微分方程。为了确定非线性方程的解,采用了著名的45阶数值龙格-库塔-费贝格方程。对模型中多个参数进行了求解,并对结果进行了绘制和总结。由于磁场的作用,能量分布加速,然后热辐射影响动量场和热场膨胀。最后,随着Eckert数的增加,Nusselt数减小。

Effects of Porous Medium in MHD Flow of Maxwell Fluid with Soret and Dufour Impacts
Non-Newtonian fluids have an inclusive range of applications in the field of heat mass transfer flow, in the movement of cooling of metallic plates, oceanography, biological fluids, melt-spinning, coating heat exchangers expertise and interruptions. In view of these applications, it examines the numerical simulation of hydromagnetic non-Newtonian maxwell fluid flow on a flat plate over a permeable medium. A discussion with Soret, Dufour, and radiation effects is presented. PDEs with non-linearities are transformed into ODEs by using similarity variables. In order to determine the solution to the nonlinear equations, the eminent numerical Runge–Kutta–Fehlberg 45th order is used. The model is solved for a number of parameters, and the resulting effects are plotted and summarized. As a result of the magnetic field, the energy profile accelerates, and then thermal radiation influences both the momentum and thermal fields to expand. Finally, with the increased Eckert number, the Nusselt number decreases.

期刊介绍: The Journal of Porous Media publishes original full-length research articles (and technical notes) in a wide variety of areas related to porous media studies, such as mathematical modeling, numerical and experimental techniques, industrial and environmental heat and mass transfer, conduction, convection, radiation, particle transport and capillary effects, reactive flows, deformable porous media, biomedical applications, and mechanics of the porous substrate. Emphasis will be given to manuscripts that present novel findings pertinent to these areas. The journal will also consider publication of state-of-the-art reviews. Manuscripts applying known methods to previously solved problems or providing results in the absence of scientific motivation or application will not be accepted. Submitted articles should contribute to the understanding of specific scientific problems or to solution techniques that are useful in applications. Papers that link theory with computational practice to provide insight into the processes are welcome.
