| Summary: | 碩士 === 國防大學中正理工學院 === 造船工程研究所 === 94 === This research uses the commerical software such as Rhino, Shipflow and Tecplot etc. to build a numerical tank. The resistances of different ship models under different load conditions are predicted at various ship speeds. In this study, we chose three different the ship models of the block coefficient including a navy battle ship "Cheng-Gong class" (CB=0.38), a ferry "Wu-Chiang" (CB=0.57) and a tanker "HSVA" (CB=0.87) are analyzed. The results of the numerical simulations are employed to compare with the corresponding experimental measurements. At first, standard computations mode of the numerical tank validate with the experimental results are conducted. Then, we can use this numerical approach to discuss the characteristics of ship resistance in different load situation; meanwhile, we want to check and test the analytical capacity and restriction of the simulation software, "Shipflow" ,which is used to solve the computational flow-field on ship design, and then we can proceed to analyze and discuss. It can be provided for the reference of the ship shape design in the future.
