- Our study -
Our initial state will be set with no velocity at the
inlet, nor at the outlet, and the pressure will be taken equal to the atmospheric
We will have to think about the conditions to put on the borders (symmetry, periodic, wall), as well as at the in and outlets.
We can already note that we will use the axisymetric solver of Fluent, because it would be too bad to forget that the bubble evolves in the space. This problem could hardly be reduced to a 2D problem!
As for the dimensions, we will make a calculation for different size of bubbles. We will then have to modify the size of our domain, as well as the grid and the size of the cells.
