The present research intends to evaluate the impact of porous media, nanofluid, and magnetic field on heat transfer of a circular channel.

It is of interest to know the impact of porosity, thickness, permeability, and thermal conductivity ratio in porous media.

The results reveal that the heat transfer rate in the central arrangement is more than the boundary arrangement.

Simultaneously, the minimum happens when the non-dimensional thickness is set to 0.6 in the boundary arrangement. Applying nanofluid and increasing the volume fraction will improve the heat transfer rate. The average heat transfer coefficient is increased when the magnetic field is applied up to the intensity of 0.5 T. Additionally, the maximum heat transfer enhancement is achieved when the thickness is 0.6 in boundary arrangement in the case of applying the magnetic field, which is estimated to be 3–5% more.
