Double-diffusive mixed convection flow towards a convectively heated stretching sheet with non-linear thermal radiation

An investigation of two dimensional double-diffusive mixed convective flow of a viscous, incompressible, electrically conducting and optically thick nanofluid over a convectively heated stretching sheet is carried out taking into account the effects of non-linear thermal radiation and partial hydrodynamic slip. A similarity solution to the governing non-linear partial differential equations subject to the boundary conditions is obtained using the efficient Spectral Local Linearization Method (SLLM). In order to study the behavioral changes in flow profiles by various non-dimensional flow parameters, the numerical solution for fluid velocity, fluid temperature, and species concentration are illustrated through figures, and the numerical values of skin friction, Nusselt number and Sherwood number are presented in tables. Nanofluid models of this kind are useful in several engineering processes requiring efficient heat and mass exchange mechanisms like catalytic and nuclear reactors, metal extraction, cooling systems and many more. © 2018 International Information and Engineering Technology Association.
