Effect of Radiation on Mixed Convection Flow of a Non-Newtonian Nan fluid over a Non-Linearly Stretching Sheet with Heat Source/Sink
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 5
Abstract
A boundary layer analysis is presented for the effect of radiation on mixed convection flow of a non-Newtonian nanofluid in a nonlinearly stretching sheet with heat source/sink. The micropolar model is chosen for the non-Newtonian fluid since the spinning motion of the nanoparticles as they move along the streamwise direction can be best described by the micropolar fluid model. Numerical results for friction factor, surface heat transfer rate and mass transfer rate have been presented for parametric variations of the micropolar material parameters, Brownian motion parameter NB, thermophoresis parameter NT, radiation parameter R, heat source/sink parameter Q and Schmidt number Sc. The dependency of the friction factor, surface heat transfer rate and mass transfer rate on these parameters has been discussed.
