Finite volume simulation of convective heat transfer through magnetic nanofluid in channel

Convective heat transfer through a water based nanofluid (Ferrofluid) is studied and simulated usingComputational fluid dynamics techniques. The geometry of flow is a 2D channel with the height of h=2mm and lengthof L=20 mm. The magnetic field action on the flow is by a permanent magnet located at the center of channel and 2mmbelow the lower wall. Homogenous model was applied to account for magnetic fields effects on the nanofluid. Numericalresults show that at the presence of external magnetic field the transport phenomena will enhance at the expense of slightincrease in pressure gradient along the channel.
