Abstract: This work is devoted to the development of a numerical model for particulate flows during phase-change processes. The model is based on the Direct Numerical Simulation (DNS) approach. The particle collisions are modelled using the hard sphere approach. The interface velocity of the melting/solidification is calculated by means of the Stefan condition for each particle. In this work we consider a two-dimensional system consisting of 40 circular ice dendrites moving up owing to the density difference in a two-dimensional channel filled with hot water (first case) and undercooled water (second case). The results of the simulations are discussed.
