Abstract

According to the resistance characteristics of trimaran, the difference of turbulence model equations was analyzed, and the suitable turbulence model of RNG k-ε for numerical calculation was selected. Nine kinds of typical solutions about outrigger hulls’ position were divided and viscous flow was calculated by using numerical simulation technology. By comparing the results of resistance, free surface and wave interference, and with reference to the related ship model experimental data, the optimal arrangement of the side body was completed.

Key words： trimaran; outrigger hull’s position; numerical simulation; resistance
