AN ANALYSIS ON WAVE GENERATION AND HULL MODIFICATION OF FISHING VESSEL

Abstract

This research is about analysis on wave generation and hull modification for fishing vessel design. Different and transverse waves are generated when a ship moves across the surface. The cross waves created by an arch and stern of the ship and the wave will form a single series of waves. The stern creates and normally separates divergent waves from the stern. The interaction between the divergent and the transverse wave system at different distances from the vessel makes the waves’ height considerably differ. For this thesis, hull modification (deep v hull) had been carried out to determine the wave generation from hull is more efficiency from the existing hull design (round bottom hull). The objectives are to design the existing and modified hull for fishing vessels and apply the simulation by using CFD software to verify which design is better. The hull design is being drawn by using Autodesk Inventor based on ship particular from selected design. Then these design is being imported from Autodesk Inventor (.stl file) into Flow3D software to get the result. Multi-block feature is being selected as method of approach in making configuration. Based on the previous research it is proven that deep v hull have more advantages in rough condition and have higher efficiency operating in desired speed compared to round bottom hull. The simulation of this project is successful and it is proven that the different total number of mesh element influence the outcome of the result. The different total of mesh element effect on accuracy of the result, animation result, mesh performance and resolution. There are few suggestion and remarks that can be used for future references on how to conduct a CFD simulation and how to have successful simulation. Finally, the author wish that this project can be continues to be researched by other UNIKL MIMET students.
