Vertical hydrodynamic tube as a working tool in a shipbuilding experiment

Abstract

Object and purpose of research. The object of the research is the flow pattern around ship models and engineering structures. The purpose is to optimize their outer lines.
 Materials and methods. The studies were carried out in a vertical hydrodynamic tunnel with a transparent test section using flow visualization methods.
 Main results. After the series of studies, technical solutions have been developed and implemented on sea-going ships and marine engineering structures. The paper shows that these studies are strongly recommended at early stages of ship design, especially for the structures with flow separations, like funnels, helipads, upper decks, air inlets, bridge spans, etc.
 Conclusion. The results indicate that the vertical hydrodynamic tunnel can be successfully used for development of outer lines for hulls and other engineering structures with flow separations.
