This article analyzes the heat transfer, non-linear thermal radiation, the Cattaneo-Christov heat flux model and velocity slip effects in hybrid nanofluid flow over a 3D moving sheet. The hybrid type nanoparticles like Ag-Cu and MoS2 and GO are suspended in working liquid. Hybrid nanoliquid is homogeneous-mixture with novel physical and chemical structures making it a promising option for improving thermal efficiency. Hybrid nanoliquids have high ability to absorb and preserve the hydrogen because of their very huge unique surface-area and distinctive and unusual nature of an each nanostructure. Nanostructure carbon atoms like graphite, graphene and few metals like molybdenum and magnesium have recently been found to store hydrogen due to their larger storage-capacity and the higher dehydrogenation and hydrogenation speeds. The system of the mathematical relation in PDEs form is converted to system of ODEs by employing suitable variables. The bvp4c tool available in computational software MATLAB is used for solving the dimensionless ordinary differential system. Furthermore, the flow expectations for each physical flow parameter like $0.1\leqslant \alpha \leqslant 1.2,$ $0.4\leqslant \beta \leqslant 1.2,$ $2.0\leqslant Pr\leqslant 5.0,$ $0.1\leqslant \gamma \leqslant 1.2,$ $0.2\leqslant Re\leqslant 0.8,$ $0.1\leqslant M\leqslant 1.2,$ $0.0\leqslant Rd\leqslant 0.8,$ $0.1\leqslant Ec\leqslant 0.4,$ $0.1\leqslant Nr\leqslant 1.2,$ $0.2\leqslant {\phi }_{1}={\phi }_{2}\leqslant \mathrm{0.5.},$ $0.1\leqslant {\rm{\Omega }}\leqslant 0.6,$ $1.5\leqslant {\theta }_{w}\leqslant 1.8,$ are discussed. The physical consequence of flow parameters against subjective flow fields are graphically highlighted with physical justifications. The vitality of prominent parameters against velocity field and temperature distribution is illustrated through graphs. The velocity field diminishes with a larger velocity slip parameter. The velocity field is enhanced by the higher estimations of the Grashof number. The consequence of temperature ratio parameter on thermal field is delineated. By enhancing the thermal relaxation parameter, the thermal field reduces.

利用非线性辐射传热研究混合纳米流体的磁化 3D 流动

本文分析了 3D 移动片上混合纳米流体流动中的传热、非线性热辐射、Cattaneo-Christov 热通量模型和速度滑移效应。混合型纳米粒子,如 Ag-Cu 和 MoS 2和 GO 悬浮在工作液中。混合纳米液体是具有新颖物理和化学结构的均质混合物,使其成为提高热效率的有前途的选择。混合纳米液体具有很高的吸收和保存氢的能力,因为它们具有非常大的独特表面积以及每个纳米结构的独特和不寻常的性质。最近发现纳米结构碳原子如石墨、石墨烯和少数金属如钼和镁可以储存氢,因为它们具有更大的存储容量和更高的脱氢和氢化速度。通过使用合适的变量,将偏微分方程形式的数学关系系统转换为常微分方程组。计算软件MATLAB中的bvp4c工具用于求解无量纲常微分系统。此外,$0.1\leqslant \alpha \leqslant 1.2,$ $0.4\leqslant \beta \leqslant 1.2,$ $2.0\leqslant Pr\leqslant 5.0,$ $0.1\leqslant\gamma\leqslant 1.2,$ $0.2\leqslant Re\leqslant 0.8,$ $0.1\leqslant M\leqslant 1.2,$ $0.0\leqslant Rd\leqslant 0.8,$ $0.1\leqslant Ec\leqslant 0.4,$ $0.1\leqslant Nr\leqslant 1.2,$ $0.2\leqslant {\phi }_{1}={\phi }_{2}\leqslant \mathrm{0.5.},$ $0.1\leqslant {\rm{\Omega }}\leqslant 0.6,$ $1.5\leqslant {\theta }_{w}\leqslant 1.8,$进行了讨论。流动参数对主观流场的物理结果用物理理由以图形方式突出显示。主要参数对速度场和温度分布的生命力通过图表说明。速度场随着速度滑移参数的增大而减小。对 Grashof 数的更高估计增强了速度场。描绘了温度比参数对热场的影响。通过提高热弛豫参数,热场减小。
