sidoubouzareah is on a distinguished road
Hi everybady,
I work on air bubbles injection within a fluid at the bottom of a cylinder in rotation using DPM model. This cylinder is not full of fluid, ie, there is a free surface (contact fluid/air).
When the air bubbles injection is applied, the bubbles are rised from the bottom of the cylinder to the free surface. in reality, when air bubbles are in contact with air (free surface), the bubbles despeare, but in my simulation, the bubbles go on their ascension (in air !!!) even the fluid doen't exist.
Is there any UDFs to make those bubbles desapearing in contact with air..... any help we be really appriciated.
