摘要

在本文中,我们讨论了外磁场和其他控制参数对悬浮碳纳米管在平板上的流动和传热的影响。流动和传热的控制方程是由Navier-Stokes和Prandtl边界层概念导出的。导出的流动和能量控制方程为非线性偏微分方程,采用适当的相似变换将其转化为具有相应边界条件的非线性常微分方程,并采用四阶龙格-库塔法进行数值求解。通过各种图形显示控制参数对流动和传热的影响,并用物理解释详细说明。本研究在玻璃纤维生产和工艺方面具有一定的应用价值。通过观察本研究的结果,我们可以得出结论,外磁场对速度和温度表现出相反的行为,并提高了换热速率。

Magneto-hydrodynamic Blasius flow and heat transfer from a flat plate in the presence of suspended carbon nanofluids
In this article, we have discussed the effect of external magnetic field and other governing parameters on the flow and heat transfer in the presence of suspended carbon nanotubes over a flat plate. The governing equations of flow and heat transfer are derived from the Navier–Stokes and Prandtl boundary layer concept. The derived governing equations of flow and energy are non-linear partial differential equation, and these equations are converted into non-linear ordinary differential equations with corresponding boundary conditions using some suitable similarity transformations and are solved numerically using fourth-order Runge–Kutta method with efficient shooting technique. Effects of governing parameters on flow and heat transfer are shown through various graphs and explained with physical interpretation in detail. This study has applications in glass-fiber production and technology. On observing the results of this study, we can conclude that external magnetic field shows opposite behaviors on velocity and temperature and it enhances the rate of heat transfer.
