Abstract
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.
