In this study, the effect of internal heat generation for Cu-water nanofluid on natural convection
heat transfer in a fluid saturated porous cavity with partially active walls has been numerically
investigated. The governing non-dimensional Darcy-Brinkman-Forchheimer equations are solved
using the finite volume approach together with SIMPLE algorithm. Benchmark results are compared
with present study which furnish that the present results are to be reliable. The addition of
nanoparticles produces an augmented heat transfer rate for low values of internal heat generation. On
the other hand, the base fluid water induces the maximum heat transfer rate than the nanofluid for high
values of internal heat generation parameter. This means that in the presence of high internal heat
generation, there is no need to add nanoparticles inside the cavity to generate the augmented heat
transfer rate.
