Abstract

In this chapter, the structured flow is simulated using both a Lagrangian and Eulerian approach for the solid phase. The discrete model presents a flow pattern of bubbles in quantitative agreement with experimentally witnessed flows. The distinctive features, such as shifting nucleation sites of bubbles and interphase coupling, are shown induced by the sharp changes of solid stress, which are created by alternating granules between fluid-like and solid-like states. These numerical results, thus, reveal the essential role of solid friction in reproducing and stabilising the structured flows.
