Bubble-induced Entrainment Between Stratified Liquid Layers
Application ID: 32491
This model is a benchmark for three-phase flow commonly used in food processing, pharmaceutical industry, and chemical processing. The results are validated against data reported in the literature.
A gas bubble rises through two layers of liquid, a lighter liquid resting on top of a heavier one. As the bubble travels from the heavier liquid, it entrains some of the heavier liquid in its wake and moves it into the lighter liquid, creating a tail of heavy liquid.
This model example illustrates applications of this type that would nominally be built using the following products:CFD Module Microfluidics Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- either the CFD Module, or Heat Transfer Module and
- either the CFD Module, or Microfluidics Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
