Design of the natural ventilation system for the fishing vessel by the CFD methods

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.
