Physics-Based Learning Models for Ship Hydrodynamics

We present the concepts of physics-based learning models (PBLM) and their relevance and application to the field of ship hydrodynamics. The utility of physics-based learning is motivated by contrasting generic learning models (GLM) for regression predictions which do not presume any knowledge of the system other than the training data provided, with methods such as semi-empirical models which i...

Advances in Cartesian-grid methods for computational ship hydrodynamics

Recent developments in computational fluid dynamics are enabling accurate simulations of full scale ship hydrodynamic flow. In particular, Cartesian-grid techniques such as volume-of-fluid and immersed boundary methods expedite computational simulations of unsteady breaking wave flows around complicated ship geometries. However, there are still a number of important numerical and modeling issue...

Contributions to modeling of bubble entrainment for ship hydrodynamics applications

Nonlinear ship waves and computational fluid dynamics

Research works undertaken in the first author's laboratory at the University of Tokyo over the past 30 years are highlighted. Finding of the occurrence of nonlinear waves (named Free-Surface Shock Waves) in the vicinity of a ship advancing at constant speed provided the start-line for the progress of innovative technologies in the ship hull-form design. Based on these findings, a multitude of t...
