Modeling two-phase (blood and oxygen) slug flow in a y-junction
1 Attachment(s)
Hi everyone,
I recently started to learn how to use Fluent, so I am in the beginning of the learning curve. I want to model a two-phase slug flow of blood and oxygen bubbles in a y-junction (as represented in the picture attached). I imported a 3D part from SolidWorks, and the y-junction is one of the several tubes in the model. My doubts are:

i have carried out similar simulations. you dont need to make a new geometry in ICEM . just import the one from solid work and clean it and define input and output surfaces.
u can use unstructured mesh tetrahedron . that will give you good results |

What do you mean by clean it? Supress all the faces, but the ones I want to model? Did you model two-phase flow? I am currently using the VOF model ( I think it is the one more appropriate for two-phase slug flow). Which one do you usually use? |
i am rather curious that why r u using VOF model?? its used for two phase fluid flow. and flow in arteries is not two phase as oxygen is absorbed by the RBCs.
and if u still want to then clean up the geometry by deleting extra surfaces. like in ur model there is thickness between outer and inner layer which may not be required. produce a 3d mesh with either tetrahedral or hexagonal elements. u can have a 2d mesh too. |
