Studies accentuating nanomaterials suspensions and flow traits in the view of their applications are the focus of the present study. Especially, the usage of such materials in biomedical rheological models has achieved great importance. The nanofluids' role is essential in the cooling of small electronic gizmos like microchips and akin devices. Having such exciting and practical applications of nanofluids our goal is to scrutinize the Maxwell MHD nanofluid flow over an extended cylinder with nonlinear thermal radiation amalgamated with chemical reaction in a Darcy-Forchheimer spongy media. The presence of gyrotactic microorganisms is engaged to stabilize the nanoparticles in the fluid. The partial slip condition is considered at the boundary of the stretching cylinder. The Buongiorno nanofluid model is betrothed with impacts of the Brownian motion and thermophoresis. The analysis of entropy generation is also added to the problem. The highly nonlinear system is tackled numerically is addressed by the bvp4c built-in function of the MATLAB procedure. The outcomes of the prominent parameters versus embroiled profiles are portrayed and conversed deeming their physical significance. It is perceived that fluid temperature is augmented for large estimates of the radiation and Darcy parameters. Moreover, it is noticed that the magnetic and wall roughness parameters lower the fluid velocity. To corroborate the presented results, a comparison of the current study with a previously published paper is also executed. An outstanding correlation in this regard is attained.
本研究重点关注纳米材料悬浮液和流动特性的研究,特别是这些材料在生物医学流变学模型中的应用。纳米流体在冷却微芯片和类似设备等小型电子设备方面具有重要作用。由于纳米流体具有如此令人兴奋和实用的应用,我们的目标是研究带有非线性热辐射和化学反应的 Maxwell MHD 纳米流体在 Darcy-Forchheimer 多孔介质中流过扩展圆柱体的流动。为了稳定纳米颗粒在流体中的位置,引入了旋进微生物。在拉伸圆柱体的边界处考虑了部分滑移条件。采用 Buongiorno 纳米流体模型考虑了布朗运动和热泳的影响。还添加了熵产生的分析。通过 MATLAB 程序中的 bvp4c 内置函数来解决高度非线性系统。描绘并讨论了主要参数对卷入轮廓的影响,以考虑它们的物理意义。结果表明,当辐射和达西参数的估计值较大时,流体温度会升高。此外,还注意到磁和壁粗糙度参数会降低流体速度。为了验证所提出的结果,还与之前发表的一篇论文进行了比较。在这方面取得了很好的相关性。
