NUMERICAL SIMULATION FOR SEDIMENTATION PROCESS OF BLOCKS BY SOLID-LIQUID TURBULENCE MODEL

A block mound is a most popular construction in coastal facilities. In a construction block mound, a numerical tool, which solves settlement/sedimentation process of blocks under high accuracy, is required. In this study, the solid-liquid turbulence flow model of high resolution is developed by introducing the Smagorinsky model as sub-grid scale turbulence model. The fundamental performance of the developed simulation model is confirmed from the relation between the drag coefficient and the Reynolds number, and the settling mode of settling two particles. In addition, the sedimentation process of multiple blocks is performed, and the effect of the introducing the Smagorinsky model is shown computationally.
