Abstract
In this paper computational fluid dynamics technology is utilized to predict the flow and heat
transfer for the porous medium. The porosity, particle diameter of three types of graphite are
studied to observe the heat transfer through the porous medium. Amorphous graphite, flake
graphite, vein graphite and copper are considered as the storage material. The porosity ranges
from 0.1 to 0.49, while the 0.02mm,0.2mm and 2mm are three values for the particle diameter.
Two types of heat transfer fluids are selected namely, ethylene glycol and mineral oil. The heat
transfer through porous medium of vein graphite is higher compared to the others, but in terms
of the overall performance of flake graphite is effective. Mineral oil gives greater values of
heat transfer due to its properties. On comparing copper with graphite, a significant difference
in the heat transfer of graphite is observed.
