In current analytic thinking, we have unveiled the influence of shapes of Al₂O₃ nanoparticles in an aqueous medium flowing in the porous space between eccentric cylinders. The flow is driven due to a sinusoidal wave on the flexible wall of the outer cylinder while the inner cylinder is rotating at a constant speed. Also, the heat transfer with mutual effects of electrical and magnetic field is observed. Equations for the different shapes of particles, i.e., brick, platelet, cylinder, and blade, are modeled. With the assumption of a long wavelength and low Reynolds number, the problem is solved analytically using the homotopy perturbation method. The impacts of the different physical parameters are discussed graphically.

偏心圆柱体上多孔介质中纳米流体的电动氢动力学中非球状纳米颗粒的流动

在当前的分析思想中，我们揭示了Al ₂ O ₃纳米颗粒形状在偏心圆柱体之间的多孔空间中流动的水性介质中的影响。当内筒以恒定速度旋转时，由于外筒的柔性壁上的正弦波驱动流动。而且，观察到在电场和磁场的相互影响下的热传递。对不同形状的颗粒（即砖块，薄片，圆柱体和叶片）的方程进行了建模。在长波长和低雷诺数的假设下，使用同伦摄动法解析地解决了该问题。图形讨论了不同物理参数的影响。
