Numerical analysis for radial MHD and mixed convection effects in peristalsis of non-Newtonian nanomaterial with zero mass flux conditions

Abstract

Here peristalsis of Carreau nanofluid in presence of mixed convection and radial magnetohydrodynamics is addressed. Flow in a curved channel is addressed. Heat and mass transfer analysis includes Brownian motion and thermophoresis impacts. Zero mass flux at the channel walls is taken. The relevant equations are first modelled and then simplified through lubrication technique. The system of non-linear equations is solved numerically. Plots for velocity, temperature and concentration are studied through numerical solution. Heat and mass transfer rates at the upper wall of the curved channel is also discussed. Enhancement in concentration is observed. Temperature of the nanoliquid enhances for larger radial magnetic parameter when velocity of the nanoliquids reduces. Significant enhancement in mass transfer rate is seen for larger theromophoretic parameter.
