Entropy Generation of Unsteady Magnetohydrodynamics Nanofluid Flow Over a Porous Inclined Stretching Surface with Velocity Slip and Viscous Dissipation
The numerical investigation of the effects of inclined variable magnetic field, velocity slip, thermal radiation and viscous dissipation on the entropy generation of an unsteady MHD nanofluid flow over an inclined stretching sheet in a porous medium has been carried out here. The non-dimensional
non-linear governing ordinary differential equations obtained after suitable similarity transformations are solved by SQLM. Effects of important factors of the model on the flow characteristics were numerically analysed and discussed in details with tables and graphs. Important physical quantities
of skin friction, Nusselt number and the local Sherwood number were calculated and illustrated on tables. The aligned angle of the variable magnetic field between 0° and 90° was found to significantly influence the fluid flow rate, temperature, mass flux and entropy generation through
the Bejan number. The velocity slip slip was found to have no signicant effects on the mass flux, however it influenced significantly the fluid flow rate and temperature. The inclination of the stretching sheet and the porosity of the medium were also found to influence the fluid flow rate,
temperature and mass flux.
