摘 要:近年来,随着人们对海洋资源探索的不断深入,水下作业装置的性能也越来越受到人们的重视。为了研究水下作业装置在偏航和俯仰状态下的水动力学特性,本文基于雷诺时均N-S方程(RANS)和RNG $ k-\varepsilon $湍流模型,对SUBOFF潜艇进行数值模拟,并与实验数据进行比较,验证了数值模拟方法的有效性和可靠性。其次,在数值模拟中研究了不同偏航角和俯仰角对水下作业装置表面压力和涡旋的影响;并在PIV试验中研究了不同偏航角和俯仰角对水下作业装置尾流速度的影响。结果表明,随着偏航角和俯仰角的增大,迎流面的表面压力逐渐增大,涡旋向背流侧发展,尾流速度阻塞区域增大,低速区范围逐渐扩大。In recent years,with the deepening of the exploration of Marine resources,the performance of underwater operating equipment has been paid more and more attention.In order to study the hydrodynamic characteristics of underwa-ter operating equipment under yaw and pitch conditions,numerical simulation of SUBOFF submarine based on Reynolds time-mean N-S equation(RANS)and RNG k-turbulence model is carried out in this paper.The effectiveness and reliabil-ity of the numerical simulation method are verified by comparison with the experimental data.Secondly,the influence of dif-ferent yaw Angle and pitch Angle on the surface pressure and vortex of underwater operating equipment is studied in numer-ical simulation.The effects of different yaw Angle and pitch Angle on the wake velocity of underwater operating equipment are studied in PIV test.The results show that with the increase of yaw Angle and pitch Angle,the surface pressure of the on-coming surface increases gradually,the vortex develops towards the backflow side,the wake velocity blocking area in-creases,and the low velocity area expands gradually.
