| Summary: | Multiphase fluid-structure interaction (FSI) involving multiphase flow and contact between immersed solids is omnipresent in numerous processes in nature, biology, and engineering applications. Examples include bio-inspired avian-aquatic vehicles, aneurysm and cardiovascular diseases in biomedical engineering, and marine vessels in ocean engineering. Of particular interest to the present study is the ice-going ships in the Arctic environment. Numerical simulation of this complex system involves modeling dynamics of disparate materials, evolving multiphase interfaces, and collisions between solids. The development of a novel three-dimensional multiphase and multiphysics computational framework based on unified continuum mechanics laws is the focus of the present dissertation. In the proposed numerical framework, we employ a fully Eulerian description for the continua of different phases, which facilitates topological changes of their interfaces during the evolution and contact processes. The interfaces and ... |
