ABSTRACT

Heat transfer characteristics of a two-dimensional steady hydromagnetic mixed-convection flow of a nanofluid over a nonlinear stretching sheet taking into account the effects of internal heat generation/absorption have been investigated numerically. The governing partial differential equations are nondimensionalized and transformed into similar forms by using appropriate similarity transformations. The transformed set of coupled nonlinear partial differential equations is solved using spectral local linearization method. The effects of different flow controlling parameters, namely, space- and temperature-dependent heat source/sink, buoyancy force, magnetic force, stretching index, Brownian motion, thermophoresis and Lewis number parameter on the flow field, heat transfer characteristics, and nanoparticles concentration, are examined.
