阻流板对高速船水动力性能影响的CFD研究
|
摘要
以水面高速过渡型船为研究对象设计船型,采用商业计算流体力学软件StarCCM+对阻流板所带来的影响进行了研究.开展了网格敏感性检验,通过对计算结果的系统分析建立了一套高精度的数值模拟方案.采用该方案对带有不同高度阻流板的船型在各航速下的黏性流场进行数值模拟,对船体兴波和压力场进行了分析.研究结果表明:阻流板可以改变过渡型船虚尾的长度,但同时也会影响尾流场波浪的波幅;阻流板改变了船体底部的压力分布形式,在阻流板前约5倍阻流板高度的范围内形成了高压.
In order to investigate the effect of interceptor on high speed vessel's hydrodynamic performance,simplified ship model was designed and commercial computational fluid dynamics software StarCCM+ was adopted.Verification of the numerical results was carried out,and a set of high-precision numerical simulation scheme was established through systematic analysis of the numerical results.The proposed scheme was then adopted to simulate the viscous flow field in the conditions of different height of interceptor and velocity.The effect and the rule of the influence induced by interceptor were obtained by the analysis of the surface wave and pressure field.Research results show that the virtual length and the amplitude of the wave behind vessel is influenced by the interceptor,and pressure distribution is changed by forming a high-pressure region in front of the interceptor,the extent of which is about 5 times of the length of interceptor.
