An effect of MHD fluid flow heat transfer using CNTs with thermal radiation and heat source/sink across a stretching/shrinking sheet

Current work studies the magnetohydrodynamics (MHD) flow of the boundary layer and heat transfer with carbon nanotubes. Furthermore, the velocity and temperature profiles are examined using different physical parameters. The governing equations are reduced to highly nonlinear partial differential equation and ordinary differential equation via similarity variables that can be solved analytically. This research focuses on the magnetohydrodynamics flow and heat transfer of carbon nanotubes across a flat plate. Water is utilised as a base fluid with two types of carbon nanotubes; SWCNT (single wall carbon nanotubes) and MWCNT (multi wall carbon nanotubes). Carbon nanotubes have a wide range of industrial, biomedical, energy production, and space cooling applications because they can improve the thermal properties of base materials. The present work of the magnetohydrodynamics fluid flow with mass transpiration using carbon nanotubes due to a stretching/shrinking surface is deliberated in the momentum and temperature profiles. Moreover, when compared to the lower branch solutions, the upper branch solutions of the magnetic field profiles are analytically stable. According to the results, in comparison to negative values, positive values of the magnetohydrodynamics flow give stable profiles. The new research is expected to serve as a foundation for the dual solution of different sorts of Newtonian fluid flows across diverse types of surfaces. The impact of the actual boundaries used in the issue is discovered, and the results are graphically shown and analyzed. The momentum and temperature profiles of water-SWCNTs are significantly higher than those of water-MWCNTs, while fluid movement slows in the nanofluid region due to nanoparticle temperature and the thickness of the thermal boundary layer increases as the volume fraction of carbon nanotubes increases.
