摘要：In this paper, we focus on numerical simulations of the wandering phenomenon in bubble plumes, obtained with a new comprehensive model. The theoretical model has been developed from the theory of multi-component fluids. We have implemented that model in a finite-element, parallel platform. After a brief discussion about the theoretical/numerical model, we describe and analyze the simulations of the wandering motion using the k-_ model. We show that this solution replicates wandering only for a relatively short period of time. The reasons for this fact are analyzed. Then, we present results obtained with the use of a Large-Eddy-Simulation (LES) approach. These results notably mimic observations of bubble plume wandering without any restriction. Finally, we employ the unsteady results of the LES approach to perform a detailed analysis of turbulence in bubble plumes.
