Research on the Hydrodynamic Performance of a Pentamaran in Calm Water and Regular Waves

As a typical multi-hull ship, the pentamaran has wider deck, higher damage stability, and low-speed seaworthiness in harsh sea conditions compared with other types such as catamaran trimaran, having more potential for becoming new type of freight merchant ship line development trend marine economy. In this paper, on basis finite volume method, numerical simulations detailed comparative analysis monohull viscous flow were carried out. The resistance prediction calm water regular waves changes each component explored. dynamic fluid body interaction (DFBI) module was used calculations water, overset mesh waves. results show that adverse effect side hulls mainly reflected range. high-speed range, influence can be ignored. At high speeds, main hull will produce favorable wave-making interference, thereby improving performance pentamaran. waves, although added increased most time, its amplitude smaller than under same wave condition. This work provides technical research design hydrodynamic
