Brownian motion and thermophoresis effects on MHD flow of viscoelastic fluid over stretching/shrinking sheet in the presence of thermal radiation and chemical reaction

Abstract The study covers the robust viscoelastic fluid stream across a stretchable surface. The analysis is conducted taking into account Brownian movement, chemical reactions, and thermophoresis. The dominant partial differential equations become regular differential equations. The method used to solve nonlinear systems is homotopy analysis. The solutions are graphically designed to illustrate the impact on speed, temperature, and concentration profiles of different parameters. The Mathematica code contains a graphical representation of the effects of different variables on speed, temperature, and distribution profiles. It is seen that, Fluid speed decreases with increases in K and M . From graphical representation, the friction of the skin on increasing K is seen to decrease. Sherwood number improves and Nusselt reduces with an increase in Nb . It is also mentioned.
