Abstract

We utilized the LIGGGHTS program package to apply the discrete element method and investigate the heat flow through a particle bed with uniform size distribution. Our aim was to compare the numerical simulations with Sakatani's thermal conductivity model. This study was conducted to establish a benchmark in our understanding of the program package and the Sakatani model.
