Computational analysis of MHD blood flow of SWCNT and MWCNT suspended nanofluid over a non-linear stretching sheet

Abstract

In this study, a computational analysis has been made for a steady, incompressible, MHD flow of the SWCNT-blood and the MWCNT-blood nanofluids past a non-linear stretching sheet of variable thickness. Darcy porous medium has been considered for fluid flow.
Consequences of homogeneous-heterogeneous chemical reactions on heat and mass transfer along with Joule heating and viscous dissipation have been explored. Appropriate similarity transformations have been applied to convert the governing equations of nanofluid flow into non-linear ordinary differential equations. Galerkin finite element scheme has been used to examine the resulting system with corresponding boundary conditions. Numerical solutions of equations are demonstrated via graphs for various physical parameters, and these graphs have also been analyzed. Comparison of velocity, thermal, and concentration profiles of SWCNT-blood and MWCNT-blood nanofluids has been established. It is concluded that flow profiles of MWCNT-blood nanofluid dominate. Concentration profile declines with homogeneous and heterogeneous reaction parameters whereas increases with the Schimdt number for both nanofluids. Then, a comparison between present and the existing results was made, and they are in good agreement. After that, several physical quantities such as the local Nusselt number, skin friction coefficient, and concentration rate are exhibited in a table.
