摘要
采用目前广泛应用的计算流体力学软件FLUENT,研究了对应侧体不同横向位置时高速五体船在静水中的水动力特性.通过计算给出了3种不同附体与主体中心距的五体船模在同一航速下的阻力系数,压力分布和自由液面波形等,并分析了附体位置对总阻力的影响.研究表明:将FLUENT软件应用于考虑自由表面的多体船水动力数值模拟和计算中是可行的,为进一步使用FLUENT软件研究多体船的水动力性能提供了依据和参考.
The popular CFD software FLUENT was used in this paper to study the hydrodynamic performance of highspeed pentamaran with different transverse distances between the mainhull and the sidehulls. Pressure dis tribution, resistance coefficient and free surface deformations are investigated for three different distances between the mainhull and the sidehulls at the same velocity. Then we discussed the effect of sidehulls position on the total resistance. Through the research, it is shown that commercial CFD software FLUENT can be used to calcu late and simulate the hydrodynamic characteristics of the multihull ship with free surface. This provides some foundation and reference on the further research of the hydrodynamic characteristics of the multihull ship with CFD software FLUENT.
