| Summary: | Heat transfer characteristics of a two-dimensional steady hydrodynamic flow
of water-based copper(Cu) nanofluid over a moving wedge, taking into account
the effects of thermal radiation, have been investigated numerically. The
Rosseland approximation is used to describe the radiative heat flux in the
energy equation. The governing fundamental equations are first transformed
into a system of ordinary differential equations and solved numerically by
using the fourth-order Runge-kutta method with shooting technique. A
comparison with previously published work has been carried out and the
results are found to be in good agreement. The existence of unique and dual
solutions for self-similar equations of the flow and heat transfer are
analyzed numerically. The results indicate that there is strong dependence
of the thermal gradient at the surface of the wedge on both velocity ratio
parameter and thermal radiation. |
