Abstract:
The rheology of non-Newtonian fluids is of an immense importance in wide range of
engineering applications involving flows over stretching surfaces along with heat and
mass transfer. The present thesis focuses on examining steady two dimensional nonlinear
flows in the presence of heat and mass transfer effects. Mathematical formulations for
nonlinear flows over vertical and horizontal stretching surfaces in the presence of
viscosity variation, magnetic field, magnetic dipole, convective and mass flux boundary
conditions are carried out in Cartesian coordinate system. Nanoparticles presence is very
beneficial for enhancing thermal properties of base fluids and has importance in
engineering processes. The shape and size of the nanoparticles play vital role in
improving thermal conductivity and this thesis emphasis on examining these effects. The
close form and numerical solutions are presented for emerging nonlinear coupled partial
differential equations by using shooting algorithm embedded with Runge- Kutta Fehlberg
method. The validity of numerical results is performed through comparison tables in the
limiting sense with available literature. The effects of pertinent physical parameters are
discussed through graphs and tabulated results are presented for skin friction coefficient,
Nusselt and Sherwood numbers
