In this present work, a numerical model of hexagonal geometrical inclusion is developed to estimate the Effective Thermal Conductivity (ETC) of the two-phase materials taking the natural convection into account. A 2-D Constant Cross Section of unit cell model is analyzed with 1-D and 2-D heat transfer using Computational Fluid Dynamics (CFD) software. Numerical analysis has been carried out by considering primary effects (Conductivity ratio, concentration) and secondary effects (natural convection) to estimate ETC of two phase materials. The developed hexagonal geometrical model also shows excellent agreement with the available experimental and analytical data.
