| 摘 要： | 运用雷诺平均N-S方程,使用CFD前处理软件ICEM CFD划分流场网格,采用RNG k-ε湍流模型,实现了对裸潜体、带指挥台围壳艇体、带十字尾翼艇体、全附体潜艇4种模型的阻力及粘性流场的数值模拟。通过数值模拟,得到了潜艇表面压力分布情况和附体附近流场的一些特性,为进一步优化潜艇的艇型和分析潜艇的流噪声打下了基础。而阻力的对比在一定程度上验证了数值模拟的可靠性。

| Abstract: | The article numerically simulated the resistance and flow field of bare submarine body with different appendages and submarine body full-appended with RNG k-ε model.And solving solutions with RANS equations.The girds were divided by ICEM CFD of CFD pretreatment software.Through numerical simulation,it obtained the submarine surface pressure distribution and some characteristics of the flow field near appendages.This is further to lay the foundation for optimizing the boat type and analyzing noise of submarine that induced by flow.And resistance contrast verified the reliability of numerical simulation to some degree. |
