- Abstract
- In recent years, to achieve a goal of reducing greenhouse gas, a fishing boat which is very economical on gas should be needed. Over the last two decades, improvements of bow part in fishing boat have been researched to reduce water resistance. Moreover, stern End Bulb research took place mostly in Japan. No one finds universal knowledge for reducing drag resistance because many fishing boats run with individual catching styles for each fish. It is also difficult to appropriate some techniques in cruise ship and tanker for fishing boat. In this study, to reduce drag resistance, improvement of body line and addition product at stern part were examined. All of the cases proposed in this study could reduce water resistance. The maximum reduction rate was around 15 to 20% comparing with the basic form (original case). Some useful improvements were found based on Computational Fluid Dynamics (CFD) works and flow visualization by Particle Image velocimetry (PIV) technique.
