Bubble rise velocity
Hi,
I am studying behavior of a large air bubble rising in water. How I can get rise velocity from Function Calculator? I have two ideas: 1.- Create a isovolume at air volume fraction between 0 and 1, and use function VolumeAve with air velocity as variable. 2.- Create a isosurface at air volume fraction = 0.5, and use function AreaAve with air velocity as variable. I get different results from two ways. What is the right option? Do you have some new idea? Thanks in advance Miguel |
Re: Bubble rise velocity
Hi Miguel, The bubble-water interface has to be very refined as you understand. There are couple of questions before answering your query:
1) Is it unsteady or steady? 2) 2D or 3D? 3) Is the solution grid independent? hasan.khanCFD@gmail.com |
