Three-Dimensional Computational Modeling of Turbulent Flow Field, Bed Morphodynamics and Liquefaction Adjacent to Munitions
Abstract
This project addresses directly to the research need outlined in MRSON-17-01 on the topic of Characteristics of Munitions Underwater and Their Environment. Large amount of observational and empirical data has been gathered in field and laboratory studies to reveal the mechanisms behind the motion of munitions. However, there are still knowledge gaps for the physical and deterministic explanation of the phenomenology. Our project aims to develop and utilize a three-dimensional (3D) computational model to predict the initiation of motion, continuous movement, and final deposition of munitions, which are important for site assessment and remediation actions. The 3D model captures the key physical processes which control the motion of munitions, including turbulent flow, sediment transport and scour, granular material dynamics, and the rigid-body motion of munitions. In addition, these processes are coupled and thus the developed model should be capable of simulating their interactions.
