Hello,
I am doing a simulation of three-flow with incompressible fluid (air-oil-water) in a pipe using COMSOL.
Here, I tried two solutions:
a) Laminar three-phase flow model with phase-field method
b) 2 Laminar two-phase flow models with level-set method (one for air-oil, and another for air-water)
In both cases, I cannot compute my model or get the wrong results.
I have done with two-flow simulation, but three-flow is quite hard
Does anyone meet this problem before? Could you give me any advice on it?
Or any solution for a three-flow simulation in COMSOL?
Thanks in advance!
Best,
I performed some numerical simulations with the LSM, see for instance:
Article Experiments on the MHD Effect on the Drainage of a LiPb Chan...
Presentation Analysis of the MHD effect on the drainage of a LiPb channel...
The LSM implemented in COMSOL is one of the possible LSM methods available in the literature and it was developed by Olsson et al. for two incompressible fluids.
It is clear that what you want to do is not possible.
You should find a LSM compatible for three phase flows and implement the equation in an equation-based modelling interface.

Hello, Sajid Ahammed
Right! I follow this paper for my second choice.
However, I cannot solve my simulation. They modify some equations with edited values. Maybe I got the wrong setup.
They modify the equations by adding auxiliary functions which are not specified. However, i suggest to read the papers by Olssen, because the verification of such a kind of medels is quote context. Its not Just to modify equations!
