Numerical model for studying axisymmetric thermal energy storages based on granular phase change materials with gaseous heat transfer fluid

•Novel numerical model of gas flows in TES based on granular PCM is proposed.•Convergence analysis of the proposed method is carried out by means of resolution tests.•Applicability of 1D approach for modelling TES with lateral heat losses is studied.•1D approach isn't accurate at high lateral h...
