摘 要:为了研究不同雷诺数对水下作业装置水动力特性的影响,采用RANS控制方程和RNG k-ε湍流模型对水下作业装置进行数值模拟。首先对SUBOFF潜艇进行了数值模拟,并与试验值进行比较,验证数值模拟的有效性和可靠性。研究在直航的状态下不同雷诺数对表面压力、涡量以及湍流动能的影响。数值模拟的结果表明,随着雷诺数增加,水下作业装置在迎流处表面压力增大,机械臂后涡量和湍流动能增大。研究结果可为水下作业装置的稳定性优化提供参考。In order to study the effect of different Reynolds number on the hydrodynamic characteristics of underwater equipment,RANS governing equation and RNG k-e turbulence model are used to simulate the underwater equipment.Firstly,the numerical simulation of SUBOFF submarine is carried out,and the validity and reliability of the numerical simulation are verified by comparing with the experimental values.The effects of different Reynolds number on the surface pressure,vorticity and turbulent kinetic energy under direct navigation are studied.The numerical simulation results show that with the increase of Reynolds number,the surface pressure of the underwater operating device at the oncoming flow increases,and the vorticity and turbulent kinetic energy of the robot arm increase.The research results can provide reference for the stability optimization of underwater operating equipment.
