摘要

包括生物和医学在内的众多行业都将从混合铁流体通过微通道的电渗 MHD 流动的尖端应用中获益匪浅。为了研究带有灰尘颗粒的混合铁流体的电渗 MHD 流动,我们使用了垂直倾斜的微通道。我们还考虑了磁场的横向分量。该流体系统中热量和质量传递的影响是本次研究的重点。偏微分方程是模拟上述物理现象的有力工具。通过使用合适的非维度变量、自由维度、广义傅里叶变换和菲克法则,经典系统被进一步分化为非维度形式。卡普托导数被用作广义化的起点。利用拉普拉斯和傅里叶混合方法,获得了速度(包含混合铁罗流体和含尘流体)、温度和浓度剖面的解析解。研究探讨了温度、应力(格拉肖夫数、施密特数和普朗特尔数)和含尘流体参数之间的相互影响。对浓度分布进行了分析,并绘制了图表来帮助直观了解结果。提供了舍伍德数、传热速率和表皮摩擦系数的平均值。值得注意的是,由于分数模型更加精确,因此在寻找可行的解决方案方面提供了更大的余地。综上所述,这些策略似乎都非常有益。与纳米流体和传统流体相比,混合 Ferro 流体能够有效地改变速度边界层,并具有更高的传热率。

Investigation of Generalized Fourier and Fick’s Law of Electro-Osmotic MHD Two-Phase Flow of Dusty Hybrid Ferrofluid Through Inclined Microchannel
Numerous industries, including biology and medicine, stand to benefit greatly from the cutting-edge use of electro-osmotic MHD flow of hybrid Ferro fluid via a microchannel. To investigate the electroosmotic MHD flow of a hybrid Ferro fluid with dust particles, we use a microchannel inclined vertically. We also take into account the magnetic field’s transverse component. The impacts of heat and mass transfer within this fluid system are the focus of this investigation. Partial differential equations are a powerful tool for modeling the aforementioned physical phenomena. The classical system is further fractionalized into a nondimensional form by using suitable nondimensional variables, free of dimensions, the generalized Fourier transform, and Fick’s rule. The Caputo derivative is used as a starting point for generalizations. The analytical solutions for the velocity (containing the hybrid Ferro fluid and dusty fluid), temperature, and concentration profiles are obtained using a mixture of Laplace and Fourier methods. The research looks at how things like temperature, stress (Grashof, Schmidt, and Prandtl numbers), and the dusty fluid parameter affect one another. The concentration distributions are analyzed, and graphs are presented to help visualize the results. The average values for the Sherwood number, the heat transfer rate, and the coefficient of skin friction are provided. Notably, the fractional models provide more leeway in finding workable solutions since they are more precise. All things considered, it seems that these strategies are quite beneficial. The hybrid Ferro fluid has the capacity to effectively modify the velocity boundary layer and has a greater heat transfer rate than both nanofluid and conventional fluid.
