Highlights

?An asymmetrical temperature distribution is observed due to the buoyant effects.

?Copper foam significantly increases heat transfer and pressure drop of the channel.

?Applying constant and alternating magnetic field enhances heat transfer rate.

?Alternating field reduces Δpwith respect to constant one leading to developedη2.

Abstract

MHD mixed convection heat transfer inside a rectangular porous channel under the effects of constant and alternating magnetic fields has been experimentally investigated. Deionized water containing magnetite particles flows through the channel filled with copper foam as a porous media. A constant heat flux condition is imposed on the top and bottom plates of the channel, while the side walls are adiabatic. Experiments were carried out atGr=7.31×106and 3
