The similar solution on the equations of the revised Cheng-Minkowycz problem
for natural convective boundary layer flow of nanofluid through a porous medium
gives (using an analytical method), a system of non-linear partial differential
equations which are solved by optimal homotopy analysis method. Effects of various
drastic parameters on the fluid and heat transfer characteristics have been
analyzed. A very good agreement is observed between the obtained results and
the numerical ones. The entropy generation has been derived and a comprehensive
parametric analysis on that has been done. Each component of the entropy
generation has been analyzed separately and the contribution of each one on the
total value of entropy generation has been determined. It is found that the entropy
generation as an important aspect of the industrial applications has been affected
by various parameters which should be controlled to minimize the entropy
generation.
