Abstract

Due to complexity of the flow field in launch tube and inconvenience for measurement, it is hardly possible to get the total measurements of the flow field in the launch tube. The main purpose of this paper is to study the movement regulation and pressure distribution of the underwater vehicle in the launch tube by means of numerical simulation. The movement regulation was calculated by engineering method. Based on the results, the flow field in the tube was real-time simulated by using Flotran module and the dynamic mesh technology, the pressure distribution of the underwater vehicle was gotten.

Key words： underwater vehicle; launch tube; flow field; numerical simulation; Flotran
