Impact of induced magnetic field on free convective flow of kerosene/water based single and multiwalled carbon nanotubes

Mathematical analysis of single and multi-walled carbon nanotubes along with two different base fluids, water and kerosene oil, subjected to a strong magnetic field with induced magnetic field effects, has been carried out. The dimensionless equations describing the fluid motion, energy, angular momentum and the induced magnetic field of nanofluid have been solved numerically by the Keller box method. Heat transfer analysis reveals that a greater volume fraction of single-walled carbon nanotubes (SWCNT) and multi-walled carbon nanotubes (MWCNT) is responsible in enhancing the heat transfer rate as compared to the convectional fluid either its water or kerosene oil. In all the cases discussed through the graphs, it is seen that the heat transfer rate is greater in kerosene oil based nanofluid as compared with the water based nanofluid. It is found the greatest in the case of SWCNT-kerosene oil nanofluid and the least in the case of MWCNT-water.
