Ship Hydrodynamics Overview

Principles

Definition

Ship hydrodynamics is the academic field and engineering discipline concerned with the interaction between ships and the water in which they operate. It investigates the fundamental principles of fluid mechanics as applied to marine vessels, focusing on phenomena such as resistance, propulsion, seakeeping, and maneuvering, which are critical for predicting and optimizing ship performance, efficiency, and safety.

Adaptive Mesh Control era

Odd M. Faltinsen [1] was a leading figure in the ship hydrodynamics adaptive mesh control era, with affiliations at Marymount University [2] during this period. His key contribution in this era was the work on Water entry of two-dimensional bodies [3], which advanced understanding of hull–water interactions, slam loads, and unsteady dynamic response, highlighting the importance of mesh adaptivity and robust modeling for realistic predictions.

Unified Interface Modeling era

Charles S. Peskin [1] is associated with Albert Einstein College of Medicine [3] and Duke University [4] during this era. His key contribution in this era, the immersed boundary method [7], provided a rigorous framework for fluid-structure interaction and moving boundary treatment, which was crucial for ship hydrodynamics modeling. Changsheng Chen [2] is associated with University of Science and Technology of China [5] and University of Pittsburgh [6] during this era. Chen [2] introduced the unstructured grid, finite-volume, three-dimensional primitive equations ocean model [8], which advanced coastal ocean simulation and enabled more accurate predictions for ship hydrodynamics in complex nearshore and shelf flows.

Integrated Immersed Boundary era

Hironori Yasukawa [1] is a researcher associated with Hiroshima University [3] and Hiroshima University of Economics [4] during the Integrated Immersed Boundary era. A central contribution of this era is the Introduction of MMG standard method for ship maneuvering predictions [7], a framework that standardized maneuvering assessments and facilitated integration with multi-physics and IBM-based workflows. Yasuo Yoshimura [2] is a prominent figure linked with The University of Tokyo [5] and Hokkaido University [6] in this era. The MMG standard method paper [7], co-authored by Yoshimura [2], helped standardize maneuvering predictions and supported design- and operation-oriented assessments within integrated, predictive simulation pipelines.
