An Assessment of Naval Hydromechanics Science and Technology

Abstract

The Department of the Navy maintains a vigorous science and technology (S&T) research program in those areas that are critically important to ensuring U.S. naval superiority in the maritime environment. A number of these areas depend largely on sustained Navy Department investments for their health, strength, and growth. One such area is naval hydromechanics, that is, the study of the hydrodynamic and hydroacoustic performance of Navy ships, submarines, underwater vehicles, and weapons. A fundamental understanding of naval hydromechanics provides direct benefits to naval warfighting capabilities through improvements in the speed, maneuverability, and stealth of naval platforms and weapons. This level of understanding requires the ability to predict complex phenomena, including surface and internal wave wakes, turbulent flows around ships and control surfaces, the performance of, sea-surface interactions, and associated. This ability, in turn, stems from the knowledge gained from traditional experiments in towing tanks, from at-sea evaluations, and, increasingly, from computational fluid dynamics.
