A numerical simulation of mixed convective and arbitrarily oblique radiative stagnation point slip flow of a CNT-water MHD nanofluid

Numerical simulation of a non-linear mathematical model governing an arbitrarily oblique slip flow of a nanofluid, with suspended carbon nanotubes in water, agitated by magnetic field, mixed convection currents and thermal radiation is carried out. The cases for both single-wall carbon nanotubes (SWCNTs) and multi-wall carbon nanotubes (MWCNTs) are taken under consideration to gain a wider perspective. Globally, heat transfer rate for SWCNTs is found to be more effective in comparison to the MWCNTs, as the former offers less resistance in terms of the overall drag or shear. In addition, it is found that the magnetic field increases the skin friction by increasing the obliqueness of the flow. Numerical validation with available studies in the literature shows excellent conformity. The results will have bearing in thermal management of the heat exchange processes occurring within the devices used in polymer industries and polymer technology.

Automated summary

The study focused on the oblique slip flow behavior of carbon nanotubes suspended in water under the influence of a magnetic field. It was found that single-wall carbon nanotubes have a more effective heat transfer rate compared to multi-wall carbon nanotubes. Additionally, the magnetic field was observed to increase skin friction by increasing the obliqueness of the flow.
