3D Magneto Hydrodynamic Slip Flow of Al50Cu50-Water and Cu-Water Nanofluids over a Variable Thickness Stretched Surface

Abstract

The current paper covers the examination of 3D magneto hydrodynamic nanofluid motion past a slendering (variable thickness) stretching surface under the influence of MHD, Soret and Dufour effects, thermophoresis, Brownian motion and slip impact. For this study, we considered the Cu-water and Al₅₀Cu₅₀-water nanofluids past a non-uniform thickness stretching surface. With the help of similarity transformations, we transformed the derived governed equations as ordinary differential equations. The mathematical outcomes determined by employing Runge-Kutta and Newton’s methods. We reveal and interpretation the graphs for different parameters like magnetic number, volumetric fraction, Soret number, Dufour number, Brownian motion, thermophoresis parameter, stretching parameter, slip parameters h₁ and h₂. We discussed the skin friction coefficient, reduced Nusselt and reduced Sherwood numbers for the influence of the pertinent parameters with the assistance of tables separately for two nanofluids (Cu-water and Al₅₀Cu₅₀-water nanofluids). Results are validated by comparing with the published results and found a favorable agreement.
