ANALYTICAL STUDY OF VARIABLE FLUID PROPERTIES AND MAGNETIC FIELD IN THIN-FILM FLOW OVER A STRETCHING STEADY SURFACE

This research paper explains the effect of dynamic viscosity on steady thin film flow of water based nanofluid GO-EG and GO-W in the presence of magnetic field, variable thermal conductivity and convective boundary condition over a stretching surface. By using the similarity transformation, the partial differential equation is converted to nonlinear third order ordinary differential equations. The analytical method (OHAM) is used to find the analytical solution of the nonlinear problem which analyze the problem. The result of important parameters for both velocity and temperature profiles are plotted and discussed. The BVPh 2.0 package is used to obtain the convergence of the problem up to 25 iterations. The skin friction coefficient and Nusselt number is explained in table form.
