In this article, we investigated the heat transfer characteristic of magneto hydrodynamic (MHD) nanofluid towards a stretching surface under the influence of radiation and hybrid nanoparticles. Here, we consider the base fluid is water embedded with Cu-Al2O3 nanoparticles with mixture of SWCNT (Single Wall Carbon Nanotubes). To transform Partial Differential Equations (PDE's) into ordinary differential equations (ODE's) equation by via similarity transformation. The changed equations are numerical solved by R-K with shooting technique in MATLAB package. The tabular and graphical results reveal the effect of miscellaneous appropriate parameters on the velocity and temperature fields along with skin friction and reduced Nusselt number. We found that the Al2O3 /H2O/SWCNT have more friction rate and reduced Nusselt number compared to the Cu/H2O/SWCNT. This result helps us to conclude that depends on manufacturing and industrial we can consider the either Al2O3/H2O/SWCNT and Cu/H2O/SWCNT mixtures.

通过悬浮单壁碳纳米管结构的金属氧化物增强牛顿流体热物理特性的综合物理见解

在本文中,我们研究了在辐射和杂化纳米粒子的影响下,磁流体动力学(MHD)纳米流体向拉伸表面的传热特性。在这里,我们认为基础流体是嵌入有SWCNT(单壁碳纳米管)混合物的Cu- Al 2 O 3纳米颗粒的水。通过相似变换将偏微分方程(PDE)转换为常微分方程(ODE)方程。改变后的方程通过MATLAB软件包中的射击技术通过RK进行数值求解。表格和图形结果揭示了各种合适的参数对速度和温度场的影响,以及皮肤摩擦和减少的努塞尔数。我们发现Cu / H 2 O / SWCNT相比, Al 2 O 3 / H 2 O / SWCNT具有更高的摩擦速率和减小的努氏数。该结果有助于我们得出结论,取决于制造和工业状况,我们可以考虑使用Al 2 O 3 / H 2 O / SWCNTCu / H 2 O / SWCNT混合物。
