Modeling Separated Multiphase Flows with Moving Mesh in COMSOL®
In part 2 of this 4-part video series on modeling turbulent flow, chemically reacting flow, mixers, and rotating machinery, you will learn how to model separated multiphase flows with the Moving Mesh approach, as well as how to include surface tension and contact angle effects. We will also discuss time-stepping requirements, the Navier-slip wall constraint, and how to incorporate mass transfer between two phases across the corresponding fluid–fluid interface.
Correction: The expression specified for computing the total number of moles leaving the domain should be "n_molest – intop1(tds.ntflux_c)". The initial negative values observed in the video for this expression are a result of the extremely coarse mesh used in the demo model.
