Abstract
In this thesis, a computational frame work to model and simulate gas-liquid-solid three-phase flows is established. A non-boundary-fitted approach is developed to easily and efficiently accommodate the moving interfaces and deforming solid. A background fluid mesh is constructed in the whole domain, whereas the gas-liquid multi-fluid interface and the solid structure are represented independently using connectivity-free interfacial points and an Lagrangian mesh, respectively. The gas-liquid interface and the solid mesh can move freely on the background fluid mesh which is represented using an Eulerian frame of reference, which avoids the re-meshing process and simplifies the computation setup significantly.
