Abstract. The effects of thermal radiation and velocity slip on the magnetohydrodynamics (MHD)
hybrid Cu-Al2O3 nanofluid over a permeable stretching surface embedded in porous medium is
reported in this thesis. The similarity transformation is used to reduce partial differential equations
to ordinary differential equations. The problem is solved using an exact analytical method. The
porosity as the new additional parameters are considered to explore the effects of porous medium.
The effect of varying parameters on the velocity and temperature profiles are illustrated in graphs,
while the skin friction coefficient and the local Nusselt number are displayed in data tabulation. The
existence of porosity causes the increasing of temperature profile and decreasing of velocity profile,
meanwhile the skin friction coefficient and the local Nusselt number is reduced.

Keywords: Boundary layer flow, hybrid nanofluid, heat transfer, thermal radiation, porous medium.
