碩士 / 國立高雄海洋科技大學 / 海事資訊科技研究所 / 104 / Xinbei-Frigate has excellent performance with a fast warship used
especially for protecting and rescuing other. The ship was described as having a
top speed of 25 Knots, and a maximal displacement of 2,482 ton. The size of
ship has a length equal to 98.5 m, and 13.2 m width as well as 5.4 m draft.
According to the actual geometry of the Xinbei-Frigate, the 3D ship’s model is
eastblished by using the CAD computer software. Then a 3D Xinbei-Frigate
model was used to set up numerical tank with FLOW-3D which is a commercial
general purpose Computational Fluid Dynamics (CFD) package. CFD can
predict the remarkable numerical results for design used. With the
high-efficency in computing nowdays, the numerical methods can achieve a
high-resolution for the soluiton of the fluid dynamics simulation which can be
utilized in each step of ships hydrodynamics.This study lies in the discussion of
applying CFD to simulate the interaction of wave and ship motion. We sought to
understand the influence of vessel speed(10 and 20 knots) on changes in water
level changes caused by different wave effects during the navigation. The
change of six degrees of freedom is singificant in ship hydrodynamics. In this
thesis, the sailing route of ship is straight so as to the sway and yaw to be equal
to zero. The detail parameters such as the change of pitch and heave and drag
force will be shown in this thesis.
