“…Nevertheless, the longest separation of S/L=0.33 is sunken among the others that expresses a good sign meaning the wider transversal distance (bigger S/L ratio) contributes to reducing the ship resistance, together with the hump depletion. This effect was also described by Souto-Iglesias et al [13].…”

“…Because of this practical, using the total resistance coefficient will cut-out some denominators like friction, wave, and other components in the calculation. Hence, the interference factor IF is expressed by: (4) Where CT (P) is the total resistance coefficient of pentamaran model and CT (M) is the total resistance coefficient of non-interference pentamaran or the sum of individual total resistance of every hull.The value of the interference factor, principally, have to be at minimum; negative if possible [13].…”

“…The graph trend of the total drag coefficient (Ct) from both tests experienced a sloping downward trend to Froude Number (Fn) 0.43, then experienced a steep decline afterwards. According to Souto-Iglesias et al (2012) this occurs due to the interference factor of wave resistance, form resistance, and viscosity. The graph trend of the total drag coefficient (Ct) to the variation of the clearance distance (S/L) decreased along with the increase in clearance (S/L).…”

“…Using the parameters, various cases are studied by varying the Froud number, the breadth of each hull and their separation. The range of separation values is chosen to be 0.2~0.5 based on the information given by reference (Thomas et al, 2011;Souto-Iglesias et al, 2012 for real Catamarans.…”

Effects of the terms associated with phi(zz) in free surface condition on the attitudes and resistance of different ships. Engineering Analysis with Boundary Elements, 95, pp. 266-285. Abstract:One of approaches for numerical simulation of a ship moving in a still water is based on the composition of double-body flow and wavy flow solved by a boundary element method. There are several terms related to the second order derivative ( of double-body flow velocity potential with respect to the vertical coordinate in the free surface conditions. Understanding of the effects of the terms is very limited so far. In many cases, they are just ignored even for ships with a high forward speed, particularly in the cases associated with multihull ships, for which no investigations on their effects have been found. This paper will present a study on the effects of the terms on the numerical prediction of the attitudes and resistance of different ships in various situations, including monohull, catamaran and trimaran with different parameters and at different Froude numbers. The results will demonstrate that the effects of the terms are significant in many cases and that considering this term may lead to the results similar to those obtained by fully nonlinear models at high Froude numbers.
