An impact of MHD and radiation on flow of Jeffrey fluid with carbon nanotubes over a stretching/shrinking sheet with Navier's slip

This article focuses on MHD flow and heat transfer of Jeffrey fluid due to a stretching/shrinking surface with carbon nanotubes, considering the effects of thermal radiation, heat source/sink parameters, and Navier's slip. Generally, solids offer higher thermal conductivity than fluids. To offer higher thermal conductivity, a new type of nanofluid is formed by suspending two types of carbon nanotubes (CNTs), i.e. single-wall carbon nanotubes (SWCNTs) and multi-wall carbon nanotubes (MWCNTs), which act as nanoparticles, into the base fluid, water. It is intended to enhance the thermal conductivity and mechanical properties of the base fluid. The structure of the problem is an equation of momentum and temperature, which are then converted into a set of ODEs to imitate the MHD flow of carbon nanotubes. The magnetic parameter, radiation parameter, and Navier slip effect significantly affect the structure of the solution to the problem. Carbon nanotubes act as nanoparticles that enhance the heat performance and mechanical properties more than the base fluid, so they have many applications in electronics and transportation. The velocity and temperature profiles, skin friction coefficient, and Nusselt number are observed and discussed through graphs. The results reveal that for stretching case, velocity profile increases with increasing the magnetic field, while the opposite trend observed in shrinking case. We notice that the SWCNT Nanofluids are better nanofluids than the MWCNT Nanofluids. We study from these final results that the usage of CNTs in most cancerous therapies can be more useful than all sorts of nanoparticles.
