Gravity in multiRegionPhaseChangeFlow #25

Closed Bumble-7 closed 2 years ago

Bumble-7 commented 2 years ago

Dear Authors, I am trying to simulate nucleate pool boiling using the multiRegionPhaseChangeFlow. Based on my understanding, the solver will be possible to handle the problem. As a test case, I tried to simulate bubble motion due to gravity. To my surprise, the bubble is actually not moving against gravity (or any other direction). I tried to see any tutorial available that simulated the buoyancy, but I came across only the coffeepot, but the motion is due to pressure difference. Please correct me if I am wrong.

Could you please clarify the same? Should I have to change anything additional to accelerationModel in constant/thermophysicalProperties.

Thank you for your time.

Apologies for the issue raised. I was able to simulate the nucleate boiling for a large length scale. On a small length scale, I am still figuring out how long to run the simulation.

Thank you
