A 3-D magnetohydrodynamic flow of hybrid nanofluid across a stretched plane of non-uniform thickness with slip effects is studied. We pondered aluminum alloys of AA7072 and AA7072 + AA7075 in methanol liquid. The aluminum alloys amalgamated in this study are uniquely manufactured materials, possessing enhanced heat transfer features. AA7072 alloy is a composite mixture of Aluminum & Zinc in the ratio 98 & 1 respectively with added metals Silicon, ferrous and Copper. Equally, AA7075 is a mixture of Aluminum, Zinc, Magnesium, and Copper in the ratio of ~90, ~6, ~3 and ~1 respectively with added metals Silicon ferrous and Magnesium. Numerical solutions are attained using R-K based shooting scheme. Role of physical factors on the flow phenomenon are analyzed and reflected by plots and numerical interpretations. Results ascertain that heat transfer rate of the hybrid nanoliquid is considerably large as matched by the nanofluid. The impact of Lorentz force is less on hybrid nanofluid when equated with nanofluid. Also, the wall thickness parameter tends to improve the Nusselt number of both the solutions.
研究了具有滑移效应的混合纳米流体在厚度不均匀的拉伸平面上的三维磁流体动力学流动。我们考虑了AA7072和AA7072 + AA7075铝合金在甲醇液体中的情况。本研究中合并的铝合金是独特制造的材料,具有增强的传热特性。AA7072合金是铝与锌的复合混合物,比例分别为98和1,并添加了金属硅、铁和铜。同样,AA7075是铝、锌、镁和铜的混合物,比例分别约为90、约6、约3和约1,并添加了金属硅铁和镁。使用基于R-K的打靶法获得数值解。通过图表和数值解释分析并反映了物理因素对流动现象的作用。结果确定,与纳米流体相比,混合纳米流体的传热速率相当大。与纳米流体相比,洛伦兹力对混合纳米流体的影响较小。此外,壁厚参数倾向于提高两种溶液的努塞尔数。
