摘要

纳米流体具有较好的热物理性质,在日常生活中非常有用,如电子设计、太阳能、热交换管和冷却系统等,因此受到人们的青睐。本研究探讨了热辐射、Cattaneo-Christov 热通量和滑移对 MHD 纳米流体沿双向拉伸/收缩表面的三维流动的影响。利用同调分析技术对变换后的常微分方程进行了分析求解。针对许多物理特征的流动进行了图解分析。研究发现,在拉伸过程中,流体的轴向和横向速度会因磁场参数、吸入/注入参数以及滑移参数而减小,而在收缩过程中则会增大。辐射参数、传热比奥特数和热松弛参数会提高纳米流体的温度。条形图还用于评估物理参数如何影响表皮摩擦系数和努塞尔特数。

Cattaneo-Christov Heat Flux and Thermal Radiation in MHD Nanofluid Flow over a Bi-directional Stretching/Shrinking Surface

Nanofluids have gained popularity due to their better thermophysical properties and usefulness in daily life such as electronic design, solar energy, heat exchanger tubes, and cooling systems, among others. We have looked at the influence of thermal radiation, Cattaneo-Christov heat flux, and slippage on three-dimensional flow of MHD nanofluid along a surface which is stretched/shrinks in both directions in this study. The transformed ordinary differential equations are solved analytically, using homotopy analysis technique. A graphical analysis for the flows for numerous physical features has been presented. It has been observed that the fluids axial and transverse velocities are decreased by the magnetic field parameter, the suction/injection parameter, as well as by the slip parameter for stretching, whereas for shrinking, they are increased. The radiation parameter, heat transfer Biot number, and thermal relaxation parameter increases the nanofluids temperature. Bar charts were also used to evaluate how the physical parameters affect the skin friction coefficient and Nusselt number.
