Computational fluid dynamics simulations of ship airwake

Computational fluid dynamics (CFD) simulations of ship airwakes are discussed in this article. CFD is used to simulate the airwakes of landing helicopter assault (LHA) and landing platform dock-17 (LPD-17) classes of ships. The focus is on capturing the massively separated flow from sharp edges of blunt bodies, while ignoring the viscous effects. A parallel, finitevolume flow solver is used wit...

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...

Dynamics of Naval Ship Design: A Systems Approach

In today's cost-constrained environment, acquisition reform is a critical component in the design, production and support of modern warships. This reform includes policies that require system acquisition programs to pursue commercial management and systems engineering practices. The application of Integrated Product and Process Development (IPPD), concurrent engineering, open systems architectu...
