- W2892446515 abstract "In the present work, in-house CFD code naoe-FOAM-SJTU is used to investigate the added resistance and motion of DTC ship at Fr = 0.052 and 0.138 in short and long head waves. The time history and Fourier series of resistance and motion is given. Validation against the experimental results shows that the computation agrees well with EFD data in high speed cases. Then, the time-averaged and the Fourier transform of hydrodynamic pressure on ship are analyzed. The time-averaged pressure shows the added resistance is mainly caused by the high pressure at the upper bow. The distribution of second harmonic pressure on the bow demonstrates the bow relative motion is closely related with the nonlinearity of resistance. It can be explained as the large bow relative motion induces the stronger non-linear change of instantaneous wetness at flare bow. The wave patterns are plotted and show that the angle which wave diverged from the ship increases as the ship speed decrease and wave length increase." @default.
