| Summary: | The study on mixed convection boundary layer of a viscoelastic fluid over a sphere which is embedded in porous medium is carried out in this thesis. Convective boundary condition on the surface at a sphere also considered. The governing partial differential equations are first transformed into non-dimensional forms and then solved numerically using the Keller-box method by augmenting extra boundary conditions at infinity. The numerical results obtained for limiting case are comparing with related outcomes in order to validate the present results. Results on the effects of the viscoelastic parameter in the presence of porosity and mixed convection on the skin friction and heat transfer as well as velocity and temperature profiles have been plotted and analyzed. |
