基于快速性和耐波性的倒V型船首改型设计

利用CFD数值模拟仿真计算,以减摇减阻为目的,在倒V形船艏的基础上进行船艏改型设计。利用商业软件FineMarine对原型和改型的静水阻力、波浪增阻、纵摇幅值、升沉幅值、波浪中的运动响应等进行数值计算,并对比计算结果,评价改型效果。计算结果表明,改型后静水阻力、规则波中的升沉和纵摇均有不同幅度的减小。

Design optimization of Inverted-V bow based on ship resistance and seakeeping

For the purpose of ship resistance and roll reduction, the inverted-V bow modification design is carried out by using CFD numerical simulation. The static water resistance, wave increasing resistance, pitch amplitude, heave amplitude and wave motion response of the prototype and the modification were calculated numerically, and the results were compared to evaluate the modification effect. The calculation results show that the static water resistance, the heave and pitch amplitude on the regular wave are reduced in different degrees after the modification.
