极地物探船破冰阻力数值仿真及试验研究

Numerical simulation and experimental research on ice breaking resistance of polar seismic ship

由于极地物探船作业的特殊性,极地海域冰况对物探船阻力会产生较大的影响。开展极地物探船冰阻力性能研究对船型开发具有重大意义。本文利用数值仿真方法和冰池模型试验方法研究极地物探船在平整冰区的航行过程,并对比分析2种研究方法的试验现象和结果。研究表明:数值仿真方法可以较为准确地反映出极地物探船在平整冰区的航行过程和冰层的破碎形式;数值仿真结果在定性上与模型试验结果比较符合,在定量上与模型试验结果之间存在可接受误差。在冰阻力预报研究领域,数值仿真方法具有重要的参考意义。

Due to the particularity of polar seismic vessels*operation,the ice level of polar sea will have a great impact on the resistance of the polar seismic ship.It is of great significance to carry out the research on the resistance performance of polar seismic ship in ice area for the development of polar seismic ship.In this paper,the numerical simulation method and ice pool model test method were used to study the sailing process of polar seismic ship in the level ice area,as the phenomena and results of the two methods are compared and analyzed.The results show that the numerical simulation method can accurately reflect the navigation process of the polar seismic ship in the ice area and the ice breaking form.The numerical simulation results are in great agreement with the experimental results qualitatively,and there are some errors with the experimental results quantitatively,but they are acceptable.The numerical simulation method has important reference value in the research of ship ice resistance performance.
