摘要

利用磁流体动力学(MHD)、热辐射和熵产研究了Stefan吹气对混合纳米液体在移动细针上流动的影响。为了便于分析,采用适当的变换将控制偏微分方程转化为一组常微分方程,然后使用Mathematica中的同伦分析方法(HAM)对其进行解析求解。本研究探讨了风机吹风、磁场和热辐射参数的变化对速度、温度和浓度分布的影响。此外,本研究还分析了局部皮肤摩擦、局部努塞尔数和局部舍伍德数的结果。增大磁场会减小速度分布。温度分布由于热辐射参数的升高而增强。此外,结果表明,斯特凡吹数的增加导致更高的速度剖面。

Stefan Blowing Impacts on Hybrid Nanofluid Flow over a Moving Thin Needle with Thermal Radiation and MHD
This investigation focuses on the impact of Stefan blowing on the flow of hybrid nanoliquids over a moving slender needle with magnetohydrodynamics (MHD), thermal radiation, and entropy generation. To facilitate analysis, suitable transformations are applied to convert the governing partial differential equations into a set of ordinary differential equations, which are then solved analytically using Homotopy Analysis Method (HAM) in Mathematica. This study investigates how varying the values of Stefan blowing, magnetic field, and thermal radiation parameters impact the profiles of velocity, temperature, and concentration. Additionally, the study analyzes the outcomes of the local skin friction, local Nusselt number, and local Sherwood number. Increasing the magnetic field reduces the velocity profile. The temperature profile is enhanced by a rise in the thermal radiation parameter. Also, the results reveal that an increase in the Stefan blowing number leads to higher profiles of velocity.
