Effect of Lorentz forces on nanofluid flow inside a porous enclosure with a moving wall using various shapes of CuO nanoparticles
Forced convection of a nanofluid in a permeable enclosure with a moving wall is presented under the effect of Lorentz forces. The mathematical modeling is formulated with the help of a stream function. The control volume finite element method (CVFEM) has been used to determine the solutions of nonlinear coupled differential equations. Shape effects of nanoparticles (NPs) with Brownian motion impact are taken into account in the present flow problem. Graphical results are demonstrated for multiple values of Darcy number, CuO-water volume fraction, Reynolds number, and Hartmann number, respectively. Computational results depict that platelet-shaped nanoparticles have a higher rate of heat transfer. Convective heat transfer augments with increase in the Darcy and Reynolds numbers while it is reduced with increase of a magnetic field.
