| Summary: | In the present article we present computational investigations of fluid–solid interaction flow. Such fluid–solid interaction flow was created in three different cavity shapes on the floor of a horizontal channel. The flow and solid particle dynamics were explored using cubic interpolated pseudo-particle method and Lagrangian scheme of Newton’s law, respectively, for two objectives. The first is to demonstrate the validity of the proposed Eulerian–Lagrangian in predicting the main characteristics of fluid–solid interaction flow. The second objective is to shed light on the dynamics of the solid particle that are present in the three types of cavities, which has not been fully covered in the literature. The results show that the particles’ trajectories are critically dependent on the magnitude of Reynolds numbers and the vortex behavior in the cavity. We also found that the highest rate of removal occurs in the early penetration of flow into the cavity, especially for the triangular cavity. Good comparisons with the previous studies demonstrate the multidisciplinary applications of this scheme. |
