The flow through a stretchable cylinder has auspicious uses in many industrial processes like thermal processing of food particles, liquid coating on photographic films and tubular heat exchangers. Motivated from these applications, heat transport through a stagnation-point hybrid nanoliquid flow past a permeable cylinder is scrutinized. Aluminum alloy and magnetite graphene oxide with water-based nanoparticles are considered. A uniform heat source/sink term is added in the energy equations. The noted novelty of this work is the application of the hybrid nanofluid along with the heat generation/absorption effect for stretchable cylinders which has not been considered in the open literature. The strong form of ordinary differential coupled equations is solved by the Runge–Kutta-Fehlberg-45 (RKF-45) numerical approach via the shooting technique. Graphical profiles are obtained and discussed at diverse physical parameters. Moreover, the drag friction and the Nusselt number are comp...

铝合金和磁铁矿氧化石墨烯通过带热源/沉孔的可渗透圆柱体的传热分析

通过可拉伸圆柱体的流动在许多工业过程中都有吉祥用途，例如食品颗粒的热处理，照相胶片上的液体涂层和管状热交换器。从这些应用的动机出发，对通过停滞点混合纳米液体流通过可渗透圆柱体的热传递进行了仔细的研究。考虑了具有水基纳米颗粒的铝合金和磁铁矿氧化石墨烯。能量方程式中添加了均匀的热源/吸收项。这项工作的新颖之处在于混合纳米流体的应用以及可拉伸圆柱体的生热/吸收效果，这在公开文献中尚未考虑。通过射击技术，通过Runge–Kutta-Fehlberg-45（RKF-45）数值方法解决了常微分耦合方程的强形式。获得图形轮廓并在各种物理参数下进行讨论。此外，拖曳摩擦力和努塞尔数都比较大。
