Direct Numerical Simulation for Sedimentation Process of Blocks by Solid/Liquid Two-Phase Flow Model

For economic construction of a landfill and an artificial reef, blocks are dumped into sea by a barge. An improvement of an accuracy of prediction of sedimentation process of blocks leads to a significant cost saving. We have developed the DEM-base solid/liquid two phase flow model to solve rigid particulate flows with high resolution and performed a direct numerical simulation for sedimentation process of an armor block unit. In this paper, a flow structure around blocks in sedimentation process is shown in detail.
