为研究船用投弃式温深计（XBT）探头在水下的运动规律，根据XBT探头的外形结构，利用FLUENT软件建立其流体动力学分析模型，并进行了网格划分，确定出边界条件。分析了XBT探头周围流场的分布情况，重点是探头的头部和尾翼处的流场分布。结果表明，探头的结构设计合理，有利于其在水下保持稳定的运动姿态。该研究可为XBT探头结构的进一步优化提供参考。

We constructed a computational fluid dynamics (CFD) model for an expendable bathythermograph (XBT) probe based on its structure and and the software of FLUENT and performed grid division and boundary conditions determination. We also analyzed the velocity field profile outside of a XBT, especially that near its head and tail. Results show that the designed probe structure is reasonable and favorable for the stability of a XBT under seawater. This paper can provide reference for the further optimization of the probe structure of a XBT.
