عنوان انگلیسی Numerical and experimental hydrodynamic analysis of catamaran with and without V-like center bow
چکیده انگلیسی مقاله Catamaran added V-like center bow (INCAT) is investigated as a wave-piercing vessel to decrease vertical acceleration and diminish slam events during sea-keeping operation. The catamaran and the vessel bow were modeled and the vertical acceleration of model was validated with experimenal test. The geometry of V-like center-bow such as slope of center bow and elevation from demi-hulls was optimized numerically in the case of 3 different slops of bow model. Considering different center bow elevation of 9.5 and 49.5 mm, the pressure contour of the INCAT vessels was compared numerically. The optimized INCAT vessel as well as the catamaran vessel was fabricated and exposed experimentally in a wavy environment with two significant wave height of 11 and 17 cm using a towing tank test. Thus hydrodynamic parameters such as vertical acceleration, heave, pitch, and resistance force were measured and compared. The results show no slam event in the environment with a wave height of 11 cm but the slam event occurr at the experiment with the wave height of 17 cm.
