I need to simulate this in fluent.
Take a bubble of radius 1 mm with internal pressure as 3 kPa, while the outside liquid is at 1 bar pressure. This bubble is at a distance of 1.1 mm from a flat surface. Gravity acts vertically down.
the bubble is of vapour.
I used multiphase model with VOF.
I created a Rectangular domain to simulate it in 2D with suitable dimensions.
I am facing problems in setting up the pressure difference in and outside the bubble , like I used operation condition has 100kPa , and boundary conditions as pressure oulet for top, right and left side of the Rectangular domain , and wall for bottom side.
Then I patched the bubble with suitable radius, but I am not able to set the presure differnce .
Could anyone help me setting the pressure difference.
