The article explores the effect of Hall current, thermal radiation, and magnetic field on hybrid nanofluid flow over the surface of a spinning disk. The motive of the present effort is to upgrade the heat transmission rate for engineering and industrial purposes. The hybrid nanofluids as compared to the conventional fluids have higher thermal properties. Therefore, in the present article, a special class of nanoparticles known as carbon nanotubes (CNTs) and iron ferrite nanoparticles are used in the base fluid. The system of modeled equations is depleted into dimensionless differential equations through similarity transformation. The transform equations are further solved through the Parametric Continuation method (PCM). For the parametric study, the physical parameters impact on velocity, energy, mass transmission, and motile microorganism's concentration profiles have been sketched. The obtained results are compared with the existing literature, which shows the best settlement. It concluded that the heat transmission rate reduces for Hall current and rises with radiative parameter. The results perceived that the addition of CNTs in carrier fluid is more efficacious than any other types of nanoparticles, due to its C-C bond. CNTs nanofluid can be more functionalized for the desired achievement, which can be utilized for a variety of applications by functionalization of non-covalent and covalent modification.
本文探讨了霍尔电流、热辐射和磁场对旋转盘表面混合纳米流体流动的影响。本研究的目的是为了提高工程和工业领域的传热速率。与传统流体相比，混合纳米流体具有更高的热性能。因此，在本文中，使用了一种特殊的纳米粒子，即碳纳米管（CNT）和铁氧体纳米粒子，作为基液。通过相似变换将模型方程系统简化为无量纲微分方程。通过参数连续法（PCM）进一步求解变换方程。为了进行参数研究，绘制了物理参数对速度、能量、传质和游动微生物浓度分布的影响。所得结果与现有文献进行了比较，结果表明该方法具有最佳的稳定性。结果表明，霍尔电流会降低传热速率，而辐射参数会增加传热速率。结果还表明，由于其 C-C 键，在载体流体中添加 CNTs 比任何其他类型的纳米粒子都更有效。CNTs 纳米流体可以通过非共价和共价修饰的功能化来实现所需的效果，从而可以应用于各种应用。
