In this article, the unsteady stagnation
point flow and heat transfer of a
nanofluid over a stretching sheet with the effects of magnetic field and porous
media is investigated numerically. The
effects of thermal radiation are also
considered. In contrast to the conventional no-slip condition at the surface,
Navier’s slip condition has been applied. The behaviour of the nanofluid was
investigated for three different nanoparticles in the water-base fluid, namely,
copper, alumina, and titanium. The simila
rity solution is used to reduce the
governing system of partial differential equations to a set of nonlinear ordinary
differential equations, which are then solved numerically by using the fourth-
order Runge-Kutta method along with shooting technique. The results
corresponding to the dimensionless velocity and temperature profiles, also the
skin friction and the reduced Nusselt
number are displayed graphically for
various pertinent parameters.
