Abstract

Highlights: Flow of magneto Jeffery nanomaterial due to a nonlinear stretching sheet is considered. Flow equations are simplified through boundary layer and small Reynold's number theory. Analytical treatment (HAM) is used to develop series solution of the non-linear system. Residual errors of ℏ plots are calculated. Boundary condition yields zero mass flux aspects. Abstract: This attempt featuring the Brownian movement and thermophoretic aspects in two-dimension through non-linearly stretchable surface. Disturbance to the flow is produced by transverse applied magnetic field. Flow governing system is transformed into non-linear system of ODE's via suitable transformation. Due to appearance of highly nonlinear terms, series solution is carried out via well-known method known as Homotopy Analysis Method (HAM) which easily tackles the non-linear system of ODE's. The finding indicates the sheet (shapes) depend on the value of parameter n and observed that in case of non-linear stretching, velocity decreases while temperature rises for larger values of n . This is because the liquid has stronger thermal conductivity. The effects of various intensity parameters are studied graphically and compared numerically.
