This work addresses a theoretical exploration of the water-based hybrid nanofluid flow over a nonlinear elongating surface. The flow is taken under the effects of Brownian motion and thermophoresis factors. Additionally, the inclined magnetic field is imposed in the present study to investigate the flow behavior at different angle of inclination. Homotopy analysis approach is used for the solution of modeled equations. Various physical factors, which are encountered during process of transformation, have been discussed physically. It is found that the magnetic factor and angle of inclination have reducing impacts on the velocity profiles of the nanofluid and hybrid nanofluid. The nonlinear index factor has direction relation with the velocity and temperature of the nanofluid and hybrid nanofluid flows. The thermal profiles of the nanofluid and hybrid nanofluid are augmented with the increasing thermophoretic and Brownian motion factors.CuO-H2Onanofluid flow has enhanced heat transfer rate thanAg-H2Onanofluid flow. On the other hand, theCuO-Ag/H2Ohybrid nanofluid has better thermal flow rate thanCuO-H2OandAg-H2Onanofluids. From this table it has noticed that, Nusselt number has increased by 4% for silver nanoparticles whereas for hybrid nanofluid this incrimination is about 15%, which depicts that Nusselt number is higher for hybrid nanoparticles.
这项工作致力于对水基混合纳米流体在非线性伸长表面上的流动进行理论探索。该流动考虑了布朗运动和热泳因素的影响。此外，本研究施加了倾斜磁场以研究不同倾斜角度下的流动行为。采用同伦分析方法求解建模方程。对转化过程中遇到的各种物理因素进行了物理解释。结果发现，磁因子和倾斜角度对纳米流体和混合纳米流体的速度分布有减小的影响。非线性指数因子与纳米流体和混合纳米流体流动的速度和温度有方向关系。纳米流体和混合纳米流体的热分布随着热泳和布朗运动因子的增加而增强。CuO-H₂O纳米流体的传热速率比Ag-H₂O纳米流体的传热速率高。另一方面，CuO-Ag/H₂O混合纳米流体的热流率比CuO-H₂O和Ag-H₂O纳米流体的热流率好。从该表中可以注意到，银纳米颗粒的努塞尔数增加了4%，而混合纳米流体的这一增加约为15%，这表明混合纳米颗粒的努塞尔数更高。
