Sliding of bubble on heated surface in nucleate boiling

Naaren · November 20, 2020, 07:38

Hi,
I am working with the solver interThermalPhaseChangeFoam (https://www.sciencedirect.com/scienc...52711016300309) to simulate the growth of single bubble. When I simulate the bubble in a three dimensional domain (Cube, with bubble at center) the bubble starts to slide on the surface. It be very much helpful if someone can suggest a solution to debug this issue.

Thank you,
M Naarendharan

My study is growth of a single bubble in saturated liquid inside a cubical domain with the bottom face having a constant temperature above the saturation temperature.

What is expected: The bubble is set at the base and is expected to leave the base after growing in size.

Problem: The bubble grows in size and starts moving on the heated plane.
