To get a better heat transmission capacity of ordinary fluids, new hybrid nanofluids (HNFs) with a considerably greater exponent heat than nanofluids (NFs) are being used. HNFs, which have a greater heat exponent than NFs, are being applied to increase the HT capacities of regular fluids. Two-element nanoparticles mixed in a base fluid make up HNFs. This research investigates the flow and HT features of HNF across a slick surface. As a result, the geometric model is explained by employing symmetry. The technique includes nanoparticles shape factor, Magnetohydrodynamics (MHD), porous media, Cattaneo-Christov, and thermal radiative heat flux effects. The governing equations are numerically solved by consuming a method known as the Galerkin finite element method (FEM). In this study, HO-water was utilized as an ironic, viscous improper fluid, and HNF was investigated. Copper (Co) and Titanium Alloy (TiAlV) nanoparticles are found in this fluid. The HT level of such a fluid (TiAlV-Co/HO) has steadily increased in comparison to ordinary Co-HO NFs, which is a significant discovery from this work. The inclusion of nanoparticles aids in the stabilization of a nanofluid flowing and maintains the symmetry of the flow form. The thermal conductivity is highest in the boundary-lamina-shaped layer and lowest in sphere-shaped nanoparticles. A system's entropy increases by three characteristics: their ratio by fractional size, their radiated qualities, and their heat conductivity modifications. The primary applications of this examination are the biological and medical implementations like dental and orthopedic implantable devices, as well as other devices such as screws and plates because they possess a favorable set of characteristics such as good biomaterials, corrosion resistance and wear, and great mechanical characteristics.
为了提高普通流体的传热能力，人们正在使用具有比纳米流体（NFs）更高热指数的新型混合纳米流体（HNFs）。HNFs 由混合在基液中的二元纳米粒子组成，可提高常规流体的 HT 能力。本研究探讨了 HNF 在光滑表面上的流动和传热特性。因此，通过采用对称法来解释几何模型。该技术包括纳米粒子形状因子、磁流体动力学（MHD）、多孔介质、Cattaneo-Christov 和热辐射热通量效应。通过使用 Galerkin 有限元方法（FEM）等方法对控制方程进行数值求解。在这项研究中，HO-水被用作粘性非牛顿流体，研究了 HNF。该流体中含有铜（Co）和钛铝合金（TiAlV）纳米粒子。与普通 Co-HO NFs 相比，这种流体（TiAlV-Co/HO）的传热水平稳步提高，这是这项工作的一个重要发现。纳米粒子的加入有助于稳定纳米流体的流动并保持流动形态的对称性。热导率在边界层状层中最高，在球形纳米粒子中最低。系统的熵通过三个特性增加：它们的分数大小之比、它们的辐射质量和它们的热导率变化。这项研究的主要应用是生物和医学领域的应用，如牙科和骨科植入物以及其他设备，如螺丝和钢板，因为它们具有良好的生物材料、耐腐蚀性和耐磨性以及良好的机械特性等有利特性。
