Abstract

Magnetohydrodynamic free convection liquid considering Hall along with ion-slip current has many engineering usages. In addition, boundary layer flow of power-law fluids due to a stretching plane possesses sundry applications in biological sciences, geophysics, and petroleum industries. Further, hybrid nanofluids are important due to their high heat transfer capability. In view of such relevance, the goal of this investigation is to analyze Hall along with ion-slip effects on thermo-fluidic flow of magnetic power-law hybrid nanofluid so as to accomplish effective cooling in the desired thermal systems. Present investigation’s novelty is adding hybrid nanostructure to power-law fluid flow influenced by Hall and ion-slip mechanism and implementation of modified Fourier’s law featured with velocity and temperature gradients. The key results are that fluid velocity amplifies with rise in ion-slip and Hall parameters. Modified Prandtl numbers and Hall parameter ameliorate heat transfer rate while ion-slip parameter diminishes it.

霍尔电流和离子滑动电流对使用修正傅里叶定律的磁性幂律混合纳米流体热性能的影响

考虑霍尔和离子滑动电流的磁流体自由对流液体在工程学上有很多用途。此外，拉伸平面导致的幂律流体边界层流动在生物科学、地球物理学和石油工业中也有广泛应用。此外，混合纳米流体因其高传热能力而非常重要。鉴于这种相关性，本研究的目标是分析霍尔效应和离子滑动效应对磁性幂律混合纳米流体热流体流动的影响，从而在所需的热系统中实现有效冷却。本次研究的新颖之处在于，在受霍尔和离子滑移机制影响的幂律流体流动中加入混合纳米结构，并实施以速度和温度梯度为特征的修正傅里叶定律。主要结果是，流体速度随着离子滑动和霍尔参数的增加而放大。修正的普朗特数和霍尔参数改善了传热速率，而离子滑动参数则降低了传热速率。
