The hybrid nanofluids have higher heat transfer efficiency than nanofluids, which has expanded their applications to include electronic cooling, production, automobile, heat transfer, solar energy, heating elements, and biomedical. The current research aims to investigate the effects of Powell-Eyring hybrid nanofluid with slip boundary conditions, and the Cattaneo-Christov heat flux model over a moving surface. By applying the appropriate transformations, the governing boundary layer system is transformed into a dimensionless non-linear ODEs. These non-linear ODEs are computed numerically by using the Keller-Box method via computational tool MATLAB. Physical flow performance and numerical results of physical parameters are obtained by using the MATLAB tool. The researchers noted that hybrid nanofluid have a higher heat transfer rate than nanofluid. The consequences reveal that the velocity profile diminishes with an augmentation in a volumetric fraction of nanoparticles parameter, slip parameter, and porous medium parameter. Furthermore, an increase in thermal radiation parameter, volumetric fraction of nanoparticle parameter, Biot number, and thermal relaxation parameter enhance the temperature layer thickness. To the researchers' knowledge, no one has previously attempted to investigate the current challenge using a mass-based hybrid nanofluid framework. Furthermore, the problem's solution is novel. Indeed, the findings of this research are unique, and the numerical results have never been reported before. Furthermore, the researchers assumed that the findings of this study will be valuable in the development of a hot-wire anemometer or a shielded thermocouple for monitoring wind velocity, among other applications.

混合纳米流体与 Cattaneo-Christov 热通量模型的比较分析:热案例研究

混合纳米流体比纳米流体具有更高的传热效率,使其应用​​范围扩大到包括电子冷却、生产、汽车、传热、太阳能、加热元件和生物医学。目前的研究旨在研究具有滑动边界条件的 Powell-Eyring 混合纳米流体的影响,以及 Cattaneo-Christov 热通量模型在移动表面上的影响。通过应用适当的变换,控制边界层系统被变换为无量纲非线性 ODE。这些非线性 ODE 通过计算工具 MATLAB 使用 Keller-Box 方法进行数值计算。使用MATLAB工具获得物理流动性能和物理参数的数值结果。研究人员指出,混合纳米流体比纳米流体具有更高的传热率。结果表明,速度分布随着纳米粒子参数、滑移参数和多孔介质参数的体积分数的增加而减小。此外,热辐射参数、纳米粒子体积分数参数、毕奥数和热弛豫参数的增加增加了温度层厚度。据研究人员所知,以前没有人尝试使用基于质量的混合纳米流体框架来研究当前的挑战。此外,该问题的解决方案是新颖的。事实上,这项研究的结果是独一无二的,而且之前从未报道过数值结果。此外,
