Abstract

Nanofluids are a new generation of fluids which help in improving the efficiency of thermal systems by improving heat transport rate and extensive applications of this class extensively fall in biomedical engineering, the electronics industry, applied thermal and mechanical engineering, etc. The core concern of this study is to examine the interaction of AlO-FeO hybrid nanoparticles of lamina shaped with blood over a 3D surface by impinging novel impacts of non-linear thermal radiations, stretching, velocity slippage, and magnetic field. This leads to a mathematical flow model in terms of highly non-linear differential equations nanofluid-effective characteristics and similarity rules. To know the actual behavior of (AlO-FeO)/blood inside the concerned region, mathematical investigation is performed numerical technique and the results are obtained for different parameter ranges. The imposed magnetic field of high strength is a better tool to control the motion of (AlO-FeO)/blood inside the boundary layer, whereas, stretching of the surface is in direct proportion of the fluid movement. Furthermore, thermal radiations (Rd) and are observed to be beneficial for thermal enhancement for both (AlO-FeO)/blood and (AlO)/blood.

摘要

纳米流体是新一代流体,通过提高热传输速率来帮助提高热系统的效率,这类流体在生物医学工程、电子工业、应用热与机械工程等领域有广泛应用。本研究的核心关注点是通过施加非线性热辐射、拉伸、速度滑移和磁场的新型冲击,研究层状AlO-FeO混合纳米颗粒与血液在三维表面上的相互作用。这导致了一个基于高度非线性微分方程的纳米流体有效特性和相似性规则的数学流动模型。为了解(AlO-FeO)/血液在相关区域内的实际行为,采用数值技术进行数学研究,并针对不同参数范围获得结果。高强度外加磁场是控制边界层内(AlO-FeO)/血液运动的更好工具,而表面拉伸与流体运动成正比。此外,观察到热辐射(Rd)对(AlO-FeO)/血液和(AlO)/血液的热增强都有益。
