Abstract

It is hard to get the pressure of high speed water column on the inner barrel through the gun water-projectile test. In order to optimize the design, the calculation model of the pressure in the body tube is established. Two dimensional numerical simulation was carried out for gun water-projectile test's high speed water column in the body tube through using Fluent software, the distribution of turbulence was described by using the k- model and the gas-liquid interface of the inside body tube was tracked through two-dimensional VOF model. It was got that simulation of the evolution of the gas - liquid interface image, as well as the pressure distribution at different time in the tube. From the simulation results, it can be seen that the high speed water column will have great pressure on the pipe wall, and the results will be of some guiding significance for the improvement of the gun water-projectile test.
