Modeling of Multiphase Flow and Free Surfaces in COMSOL - Archived
The latest version of the COMSOL Multiphysics® software introduces great improvements in the usability and capabilities for modeling dispersed and separated multiphase flows.
Dispersed flow interfaces, such as the Bubbly Flow, Mixture Model, and Euler-Euler Multiphase Flow interfaces, are easier to use and are much less sensitive to poor starting guesses. The multiphase flow functionality has been extended with a Phase Transport interface that allows you to define an arbitrary number of phases, like water, oil, gas, and dispersed solid particles. This also makes it possible to model bubble and particle size distributions in dispersed flow models; for example, to model bubble or droplet breakup between multiple bubble or droplet sizes.
The multiphase flow interfaces for separated flow models, which use so-called surface tracking methods, are now more stable and less sensitive to coarse meshing in underresolved problems. The performance of the Level Set interface is substantially improved. Both the Level Set and Phase Field interfaces can be easily combined with other physics phenomena; for example, to model fluid-structure interaction (FSI) coupled to two-phase flow.
In this webinar, we will demonstrate the use of the new and improved multiphase flow interfaces for simulating bubble breakup in dispersed flows; modeling free surfaces with separated flow models; as well as combining multiphase flow with other physics, such as in FSI and electric fields (Taylor cone). The audience can ask questions throughout the presentation or during the Q&A session at the end of the webinar.
