Influence of Nanofluids on Magnetohydrodynamic Heat and Mass Transfer Over a Non-Isothermal Wedge with Variable Viscosity and Thermal Radiation

This analysis focuses to study theoretically the influence of the thermophoresis particle deposition and Soret-Dufour effects on the magnetohydrodynamic convective flow, heat and mass transfer characteristics of an incompressible Newtonian electrically conducting nanofluid having temperature-dependent viscosity over a non-isothermal wedge in presence of thermal radiation and viscous dissipation. The governing boundary layer equations are written into a dimensionless form by similarity transformations. The transformed coupled non-linear ordinary differential equations are solved numerically by applying a fifth-order Runge-Kutta-Fehlberg scheme with shooting technique using appropriate boundary conditions for the various values of physical parameters. The effects of various physical parameters on the dimensionless velocity, temperature and concentration profiles are depicted graphically and analyzed in detail. Favorable comparisons with previously published work on various special cases of the problem are obtained. Numerical results for local skin-friction co-efficient are tabulated for different physical parameters.
