在本篇論文中，透過計算流體動力學(CFD)方法做水平平面運動試驗(HPMM)得到全尺度DARPA SUBOFF模型的流體動力係數。利用動網格方法，使模型做振盪運動基於非穩態流體體積法的雷諾平均求解器(RANS)。為了模擬水平平面運動試驗中的運動，包含縱移、橫移、橫擺、橫擺運動加漂流角、橫搖以及直線運動加上不同的偏流角，動網格方法中的平滑法、動態分層法及局部重建網格法都已經建立的很完整。因此，在不同的擺放模式下裸船(構型三)和裸船加上帆罩及舵板(構型八)所得到的流體動力係數會進行比較，其中構型三的模擬與實驗比較得到了不錯的結果，構型八則提供完整的縣性及非線性的流體動力係數。

In this study, hydrodynamic derivatives of a full-scale Defense Advanced Research Projects Agency (DARPA) SUBOFF model were calculated by computational fluid dynamics (CFD) modeling of horizontal planar motion mechanism (HPMM) tests. The unsteady volume of fluid (VOF)-based Reynolds Averaged Navier-Stokes (RANS) solver was performed on oscillation motions of the model by adding a comprehensive dynamic mesh strategy. In order to simulate motions of pure surging, pure swaying, pure yawing, yaw motion with a constant drift angle, pivot rolling motion, as well as the straight-line motion with drift angles in the HPMM tests, the dynamic mesh strategy consisting of the smoothing method, the dynamic layering method and the local remeshing method has been well established. Consequently, the hydrodynamic derivatives analyzed in the yaw mode, the pitch mode and the roll mode for both the bare hull (configuration 3) and the bare hull with sail and rudders (configuration 8) would be compared to the experimental data of configuration 3 model. The simulation results of configuration 3 are basically in good agreement with the experimental data; the ones of configuration 8 provide for the complete database of linear and non-linear hydrodynamic coefficients.
