We think that we succed to create a realistic geometry
and a unstructured mesh, which was a great part of the work. It's a pity
that we have obtained strange results for the simulations even if the global
behaviour of the flow in downstream of the bubble and the sphere is in
"good" agreements with the theory. We realize that with a industrial code
even if study flow seems not too difficult it is not always easy to obtain
acceptable results.
Nethertheless, this task allowed us to manipulate prebfc
and to improve our level in the using of the industrial code Fluent.
We suggest futur tasks to resolve these problems:
