This communication briefings the roles of Lorentz force and nanoparticles aggregation on the characteristics of water subject to Titanium dioxide rotating nanofluid flow toward a stretched surface. Due to upgrade the thermal transportation, the nanoparticles are incorporated, which are play significance role in modern technology, electronics, and heat exchangers. The primary objective of this communication is to observe the significance of nanoparticles aggregation to enhance the host fluid thermal conductivity. In order to model our work and investigate how aggregation characteristics affect the system's thermal conductivity, aggregation kinetics at the molecular level has been mathematically introduced. A dimensionless system of partial-differential equations is produced when the similarity transform is applied to a elaborated mathematical formulation. Thereafter, the numerical solution is obtained through a well-known computational finite element scheme via MATLAB environment. When the formulation of nanoparticle aggregation is taken into consideration, it is evident that although the magnitude of axial and transverse velocities is lower, the temperature distribution is enhanced by aggregation.
本通讯介绍了在二氧化钛旋转纳米流体流向伸展表面的情况下，洛伦兹力和纳米粒子聚集对水特性的作用。由于提高了热传输性能，加入了纳米粒子，这在现代技术、电子和热交换器中发挥着重要作用。本通讯的主要目的是观察纳米粒子聚集对增强主体流体导热系数的重要性。为了对我们的工作进行建模并研究聚集特性如何影响系统的导热系数，已经在分子水平上对聚集动力学进行了数学介绍。当相似变换应用于详细的数学公式时，会产生无量纲的偏微分方程组。然后，通过 MATLAB 环境中的著名计算有限元方案获得数值解。当考虑纳米颗粒聚集的公式时，很明显，尽管轴向和横向速度的大小较低，但聚集会增强温度分布。
