Ceramic foams are used in thermal application both as insulations and heat exchangers. Understanding the effect of foam morphology on their effective thermal conductivity is important for design engineers. In this work, the effects of parameters such as: porosity, cell inclination angle and ligament tapering are studied using Finite Elements (FE) method. For the purpose, an algorithm for the generation and meshing of tetrakaydecahedra was implemented and steady state thermal simulations performed. Results compared with experimental data from the literature showed good agreement. A strong decrease of thermal conductivity was found by increasing porosity and ligament tapering, while a less significant increase was noticed on increasing cell inclination angle.
