Abstract

当水下航行体在极地环境下近冰面航行时，水下冰面容易对航行体产生不同程度的干扰。本文为探究水下航行体在近冰面航行时，冰面对其下方航行体水动力性能的干扰情况，以SUBOFF型潜艇为研究对象，采用格子玻尔兹曼方法模拟流体，流体与固体的复杂动边界使用浸没移动边界法进行处理，构建结构物-水相互耦合作用的数值模型。对航行体不同航速，不同冰体下表面形态以及航行体与冰面不同垂向间距，各个因素对水下航行体受到的水动力干扰情况进行分析。计算结果表明：航行体航速越快，航行体与冰面垂直距离越小对航行体的水动力影响越大；另外，不同冰体形态也对航行体的水动力影响也各有差异。本文建立的数值模型为近冰面水下航行体的安全航行问题提供参考。
