Abstract: Porous materials represent a new era in the area of advanced materials. Many research works have been carried out on porous ferrous metals. This project tries to develop an open cell porous grey cast iron specimen. The method called “Casting using sand balls” was used for the development of open cell grey cast iron specimens. It consists of four stages in production such as making of sand balls, making of the mold, pouring of the molten metal, and removal of sand balls. The Transient Plane Source (TPS) experiment is done on the casted specimen to find the thermal conductivity. This experimental value of thermal conductivity of porous specimens was compared with solid specimen. A numerical analysis was also done to find out theoretical thermal conductivity which is used as thermal properties in the Finite Element (FE) Analysis of the porous model. The nodal temperature distribution was plotted for both porous and solid specimens from FEA results
