Unsteady MHD boundary layer flow of nanofluid over a stretching sheet with variable viscosity and viscous dissipation
Srinivas Maripala, Kishan Naikoti
The unsteady magnetohydrodynamics free convection flow of an incompressible viscous nanofluid past a stretching surface is analyzed by taking into an account the variable viscosity and viscous dissipation under the influence of Hall currents effect. The boundary layer equations are governed by coupled nonlinear partial differential equations and transformed into a set of non-linear ordinary differential equations with the help of local similarity transformations. The coupled non-linear ordinary differential equations have been solved numerically by the implicit finite difference method. The effects of flow parameters such as magnetic parameter M, Hall parameter m, Prandtl number Pr, Eckert number Ec, thermophoresis parameter Nt, Brownian motion parameter Nb on axial velocity, transverse velocity, temperature and concentration profiles are investigated analyze through graphs. Physical quantities such as skin friction coefficient –f” (0), heat transfer coefficient –θ’ (0) and mass transfer coefficient ϕ’ (0) are also computed and are shown in table.
