Physics and learning based computational models for breaking bow waves based on new boundary immersion approaches
… of physics-based and learning-based models. Methods which immerse physical boundaries on Cartesian background grids can model complex topologies and are well suited to study breaking bow waves. However, current methods such as Volume of Fluid and Immersed Boundary methods have numerical and …

Development of an Immersed Boundary Method for the Simulation of Moving Bodies at Fluid-fluid Interfaces
… others. This thesis presents the development of Immersed Boundary Methods (IBMs) coupled to a two-phase incompressible flow solver. The phases are treated as immiscible, and are modelled using the Volume-of-Fluid (VOF) method. The methods developed to include the effects of surface tension and …

Fish swimming optimization and exploiting multi-body hydrodynamic interactions for underwater navigation
… even extract energy from these flow features. Immersed Boundary Methods (IBMs) are particularly well suited to simulate flows resulting from several moving bodies. In this thesis, the difficulty of most existing IBMs to accurately handle Reynolds numbers higher than 103 is discussed, and a …

CFD simulation of polarization phenomena in direct contact membrane distillation systems
… uses an efficient combination of finite-volume methods in space, projection methods in time, and recent advances in immersed boundary methods for the spacer surfaces. For DCMD systems without spacers, we perform a comprehensive parametric study of polarization phenomena for a wide range of feed …

Implementation of the phase field method with the Immersed Boundary Method for application to wave energy converters
… development is then coupled with the present Immersed Boundary Module which is used to simulate the presence of moving bodies and again verified against test cases, such as the Dam Break problem with a vertical obstacle and heave decay of a partially submerged buoyant cylinder. Finally, a …
