Abstract

Abstract:

In order to more reasonably evaluate the survivability of the floating bag device of a special torpedo, a three-dimensional numerical flume was established based on the finite element method and the commercial software Fluent. The boundary wave method and the source item method were used to realize the wave-making and wave-eliminating functions of the water tank, and the wave conditions of the sea area in the operation of the lightning-floating device were simulated. On this basis, the fluid-solid coupling model of the interaction between wave and thunder floc structure was established to analyze the influence of ocean waves on the survivability of the thunder floc structure. The simulation results showed that the wave generated by the three-dimensional numerical flume had good stability and repeatability, and the position and value of the maximum stress response of the floating bag were obtained, which provided an important numerical reference for the design and improvement of the experimental torpedo with floating bag device.

Key words: experimental torpedo with floating bags, numerical sink, Fluent, boundary wave making, source wave elimination, fluid solid coupling
