Fishing vessel hull design and towing resistance calculation by the CFD methods

Sugalski K.

Zeszyty Naukowe / Akademia Morska w Szczecinie

2014

nr 40 (112)

27--30

Hull resistance and propulsion calculations are the basis of every ship design. In this paper, application of the computational fluid dynamics are presented together with the results of towing resistance of the model of stern trawler. The practical use of CFD in the preliminary vessels' design process were presented at the stern trawler vessel type.All calculations had been performed in the free CFD software called OpenFOAM. This is set of C++ programming language libraries, designed to solve Navier-Stokes equations.

In this paper, application of the computational fluid dynamics has been presented in the process of design natural ventilation system for the fishing vessel. There are two main types of ventilation systems: natural ventilation which is used on small fishing vessels and sport craft boatsand, and forced ventilation. This type of ventilation is a common solution on all types of merchant ships. In this paper, solution of the velocity filed in the cargo hold space of the fishing vessel had been presented. Natural ventilation system has been validated using the CFD (Computational Fluid Dynamics). All calculations had been performed in the free CFD software called OpenFOAM.
