A model of granular flow in the regime of a moving bed under conditions of granular phase ablation is developed. The model is based on the well‐known two‐layer representation of stratified slurry flow, which assumes a dynamic equilibrium between the bottom (granular) layer and the upper layer of solids‐liquid suspension. The mass transfer rate from the bottom layer to the upper one is defined on the basis of digestion model for a single spherical lump. The model developed allows estimation of the lengths required for the total digestion of lumps in a moving bed and the axial pressure gradient distribution for different flow regimes.
