Visualization of the Flow Field Around a Generic Destroyer Model in a Simulated Turbulent Atmospheric Boundary Layer.

Abstract

An experimental flow visualization study was performed on a rectangular block and other elements that could be assembled in the form of a generic destroyer ship model. The purpose of the study was to visually analyze the flow field around the model in a simulated open ocean atmospheric boundary layer. To ensure correct simulation of the atmospheric boundary layer, both velocity profile and longitudinal turbulence intensities were matched. For the actual flow visualization studies, two techniques were used. During the on-body portion of the study, the ultraviolet lighting/fluorescent minituft technique was used. For the off-body portion, helium bubble system, with a neutral density centrifuge, was utilized. Both techniques produced excellent photographic results and allowed for direct comparison of the flow fields using the two flow visualization techniques.
