This work investigates a hydrodynamic problem involving the Fe3O4-Water nanofluid. The novelty of this investigation lies in fact that nanofluid free convection is evaluated within specific rectangular enclosure having finned absorber plate as top wall, heated by solar energy. fins below permit to enhance heat transfer towards A numerical simulation carried out order predict influence Rayleigh ...

Horizontal convection in a rectangular enclosure driven by a linear temperature profile along the bottom boundary is investigated numerically using a high-resolution spectralelement discretization in space and a third-order time integration scheme for velocity and temperature fields. A Boussinesq approximation is employed to model buoyancy. The emphasis of this study is on the scaling of Nussel...

This work reports an analytical solution for the solidification of a superheating phase change material PCM contained in a rectangular enclosure with a finite height. The analytical solution has been obtained by solving nondimensional energy equations by using the perturbation method for a small perturbation parameter: the Stefan number, ε. This analytical solution, which takes into account the...

An analytical formulation has been developed to evaluate the shielding effectiveness (SE) of two coplanar rectangular metallic enclosures with a circular aperture excited by an internal electric dipole source. The formulation consists of three parts: First, the near-field electromagnetic interference (EMI) of the electromagnetic leakage from the aperture is represented by the electric dipole in...

Using an implicit finite difference method, the effect of Joule heating on the magnetohydrodynamic natural convection in an inclined rectangular enclosure with internal heat generation has been performed. The left and right walls of the enclosure are maintained at a constant temperature while the bottom and top walls are kept insulated. The values of the governing parameters are the Hartmann nu...
