This article addresses the dynamic of three-dimensional rotating flow of Maxwell nanofluid across a linearly stretched sheet subject to a water-based fluid containing copper nanoparticles. Nanoparticles are used due to their fascinating features, such as exceptional thermal conductivity, which is crucial in modern nanotechnology and electronics. The primary goal of this comprehensive study is to examine the nanoparticles size and shape factors effect on the base fluid temperature. The mathematical model contains the governing equations in three dimensional partial differential equations form, and these equations transformed into dimensionless ordinary dimensional equations via suitable similarity transformation. The bvp4c technique is harnessed and coded in Matlab script to obtain a numerical solution of the coupled non-linear ordinary differential problem. It is observed that the greater input of rotating, Deborah number, and magnetic parameters caused a decline in the fluid primary and secondary velocities, but the nanoparticles concentration enhanced the fluid temperature. Further, a substantial increment in the nanofluid temperature is achieved for the higher nanoparticle's diameter and shape factors.
本文研究了麦克斯韦纳米流体在含铜纳米颗粒的水基流体作用下，跨越线性拉伸薄板的三维旋转流动特性。使用纳米颗粒是因其具有迷人的特性，如卓越的热导率，这在现代纳米技术和电子学中至关重要。这项全面研究的主要目标是考察纳米颗粒尺寸和形状因子对基液温度的影响。数学模型包含三维偏微分方程形式的控制方程，这些方程通过适当的相似变换转化为无量纲常微分方程。利用bvp4c技术并在Matlab脚本中编码，以获得耦合非线性常微分问题的数值解。结果表明，增大旋转、德博拉数和磁参数会导致流体一次和二次速度下降，但纳米颗粒浓度会提高流体温度。此外，对于较大的纳米颗粒直径和形状因子，纳米流体温度会显著升高。
