Numerical study of heat and mass transfer of williamson hybrid nanofluid (CuO/CNT's-water) past a permeable stretching/shrinking surface with mixed convective boundary condition

Abstract

The present paper deals with the hybrid nano fluid, for this we have used Single and Multi-wall carbon nano tubes along with CuO and Water. The inclined magneto-hydrodynamics is considered along with Hall effect, soret and dufour for the impact on Williamson fluid flowing through porous medium over stretching/shrinking lamina having suction and injection in consideration. Heat and mass convective boundaries are taken to solve the nonlinear problem using shooting method and bvp4c MATLAB solver. The study shows the comparison between nanofluid (Cuo-Water, SWCNT-Water and MWCNT-Water) and found that the hybrid carbon nanotubes possess excellent result in skin friction and local Nusselt number compared to the SWCNT-water and MWCNT-water.Then the effect of different parameters are analysed through graphical representation and data tables.
