Contribution to Conference
This paper applies Computational Fluid Dynamics (CFD) method to study the wave effect on ship oblique towing test. Obliquely towed model is S-175 bare hull with an oblique angle of 10 degrees. The ship motion involves incoming head waves of various wavelengths, and overset mesh method is used to simulate wave-induced ship motion. First part of this study tests the grid sensitivity of present CFD model, observing the near-wall grid effect on body forces. Second part is about the computation on ship oblique towing motion in waves. Ship motion and wave drift force are compared with experiment, and further CFD analysis investigates how oblique condition affects wave pattern and the distribution of fluid turbulent kinetic energy.
