What is A Numerical Analysis of ConfinedTurbulent Bubble Plumes about?
Complex, 3D mixing of single- and multi-phase flows, in particular by injection of gas and creation of bubble plumes, occurs in a number of situations of interest in energy technology, process and environmental engineering, etc. For all these applications, the basic need is to determine the behaviour of the bubble plume and the currents induced by the ascending gas plume in the surrounding liquid and thereby the consequent mixing in the body of the liquid.A six-equation, two-fluid model was utilized and transient calculations were performed to study the plume growth, the acceleration of the liquid due to viscous drag, and the approach to steady-state conditions. All calculations were performed using the commercial CFD code CFX4, with appropriate modifications and code extensions to describe the interphase momentum forces and the turbulent exchanges between the phases. Since the k-e is a single-phase model, an extended version was used, with extra source terms introduced to account for the interaction between the bubbles and the liquid. A new model was advanced to relate turbulent bubble dispersion to statistical fluctuations in the liquid velocity field, affecting the drag and lift
