摘要
Abstract
The pentamaran was proposed as another new concept of multihull ship form following the contemporary trimarans. The investigation on the wave resistance characteristics and resistance reducing outrigger configuration is necessary for its application. According to the Cochin function linear superposition and coordinate transformation principle of the central hull and four outriggers of pentamarans, the expanded and whole arithmetic for the Cochin function were brought forward to solve the multihull ship wave resistance, which reduced the general wave resistance expression for monohulls, trimarans and pentamarans. CFD software was used to make further analysis on the characteristics of pentamaran wave resistance and of the central hull and outriggers wave interference, and the outrigger configuration optimization based on the wave pattern observation of CFD numerical simulation free surface was proposed for the pentamarans, which provided a perceivable qualitative judgment resort to the wave making feature for various configurations of the pentamaran. And according to the results of linear wave resistance and viscous hydrodynamic CFD calculation, we proposed the pentamaran optimized configurations with practical application significance. It is concluded that present linear theory of the potential flow and CFD method for the pentamaran resistance calculation and the pentamaran configuration based on that have important significance in future practical application.关键词
