Abstract :
Underwater gas jet produces a complex unstable multiphase flow field, which is involved in different technological fields. The VOF multiphase flow model and the RNG κ - ε turbulence model were adopted to predict the structure of underwater gas jet flow field and to reveal the development of transient flow. The features of the developing process of the two phase flow, and the basic characteristics of the jet flow under the influence of the complex compression and expansion waves were revealed. The simulated results are in good agreement with experimental data, and thus indicate the accuracy of the proposed method.
