潜艇应急上浮运动的CFD预报

CFD prediction of submarine motion during emergency surfacing

  • 摘要:
      目的  潜艇应急上浮性能是潜艇生命力的一个重要方面,与潜艇的安全性密切相关。为了掌握潜艇应急上浮过程中的运动规律,
      方法  通过建立带有上层建筑非水密区域及流水孔的潜艇结构模型,采用重叠网格方法离散计算域求解RANS方程获得潜艇受到的水动力,并联合六自由度运动方程对应急上浮时的运动姿态进行求解。
      结果  得到了上浮过程中纵倾角、横倾角和横摇周期的变化情况,模拟出了潜艇零航速上浮时水下、出水及水面振荡全过程的运动姿态。
      结论  研究成果可用于潜艇应急上浮的操纵与控制模拟,为潜艇总体性能设计提供技术支撑。

     

    Abstract:
      Objectives  Emergency surfacing is an important aspect of submarine vitality which is closely related to submarine safety. In order to master the motion laws of submarine during emergency surfacing performance,
      Methods  this paper establishes a structure model of submarine with non-watertight zone and drain-holes in the superstructure, solves the RANS equation to obtain the hydrodynamic force through discretizing the fluid field with an overset grid method, and combines solid motion equations to obtain the submarine's attitude.
      Results  The simulation successfully calculates variables in terms of roll angle, pitch angle and oscillation period, and predicts the attitude of the submarine when it is underwater, out of water and oscillating on the surface.
      Conclusions  The results of this paper can be applied to the simulation of submarine emergency surfacing operation, thereby providing technical support for the overall design of submarines.
