porosity on heat transfer of RB system was studied by changing the diameter and distribution of the plexiglass sphere. Rayleigh number (
Ra
) changed from 5×10
7
to 2×10
9
and Prandtl number (
Pr
) was fixed at 5.5. The results show that under low
Ra
numbers
the filled spheres have almost no effect on the heat transfer of the RB system; under high
Ra
numbers
the heat transfer of the RB system is enhanced
with a maximum increase of 16%.
