| Summary: | 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. |
