Large-eddy simulation and integral model parameters for multiphase plume in stratified flow

Characteristics of laboratory-scale bubble-driven buoyant plumes in a stably stratified quiescent fluid are studied using large-eddy simulation (LES). This dataset consists of four LES cases with identical source buoyancy flux, but with four different bubble rise velocity (corresponding to different bubble diameters). Based on the dataset, the inner/outer double plume structure and the peel/intrusion process as well as their dependence on the bubble rise velocity are illustrated. The details of the simulations and data analyses as well as the visualizations of the data can be found in the paper “Large-eddy simulation and parameterization of buoyant plume dynamics in stratified flow” (Journal of Fluid Mechanics, DOI:http://dx.doi.org/10.1017/jfm.2016.191).
