Abstract
In order to study the motion of Expendable Bathythermograph (XBT) probe, the transient dropping process is numerically simulated by using Fluent software. In the paper, the dynamic mesh method, the 6DOF solver and the volume of fluid (VOF) model are used in Fluent. The trajectory, speed and rotating speed of the probe are investigated, and we also analyze the influence of the tail fin’s shape on the rotating speed. The numerical results show that the trajectory and key velocity of XBT probe are in accordance with the relevant research results. And we could get more detailed information than theory or experiment methods. The work can provide a research basis for the research on the underwater motion, stability and structure design of the XBT probe.
