| Zusammenfassung: | The wave flow pattern builds up along the hull and expansion flow behind the hull is absorbing the energy from the ship as a resistance. The ship's resistance and the behaviour of its components are significant in estimating the propulsion of the ship, which positively influences fuel consumption. The aimed of this work was investigating the influence of two hull forms and its outriggers arrangement in pentamaran systems. The investigating was in wave resistance, interference, and far-field wave spectrum. This study focused on warp-chine and Wigley hull shapes by comparing a computation which was based on Michell's thin ship theory and various tests in clearance and stagger of side hulls. The results of this study founded the resistance coefficients based on Michell's approach agreed with towing test results at Fn > 0.5. Besides, wave resistance for warp-chine configurations was established to be much better than Wigley except at Fn < 0.5. High coefficient reduction for warp-chine hulls was generated with a setting where the main hull to side hull on a formation as an arrow trimaran near to Kelvin angle. As for Wigley, the high reduction was produced by a configuration where the front-side hull and the stern-side hull were in line. Then, captured wave patterns of the towing test exhibited a fit visual with the computation, in which Wigley hulls produced a more significant wave than warp-chine hulls. |
