Non-linear heat and mass transfer in a thermal radiated MHD flow of a power-law nanofluid over a rotating disk

The steady MHD flow of a power law nanofluid due to a uniform rotation of an infinite disk is studied with heat and mass transfer. The viscous dissipation has been comprised in the energy equation. The governing PDEs are reduced to a set of ODEs; using the generalized Von Karman similarity transformations; for which finite difference numerical scheme is implemented along with the associated boundary conditions. The non-Newtonian fluid characteristics affect the fluid velocity, temperature and concentration of suspended nanoparticles. The significant effects of thermal radiation, Brownian motion and thermophoresis diffusion are involved. The skin friction coefficients in addition to the heat and mass transfer rates are defined and calculated considering the variation of all flow parameters. The present results are verified and compared with literature.
