Hello
How can I get the velocity plot u(t) of a rising bubble using COMSOL like in this tutorial https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://doc.comsol.com/5.6/doc/com.comsol.help.models.cfd.rising_bubble_2daxi/models.cfd.rising_bubble_2daxi.pdf&ved=2ahUKEwj72fCBlPeGAxXEAtsEHcouCCYQFnoECCIQAQ&usg=AOvVaw0KNnlMF2GFBm7hHgylNWEC
This is a tutorial and its .mph (COMSOL) file available please download and check its steps inside the file. I hope it will help you.
Dear Imran Shah
Thanks for your replay, the tutorial that I've mentioned doesn't contain the desired plot that I'm seeking I'm looking at how to get the specific phase's velocity such as in this tutorial, the bubble. I'm not sure if I should use the level set or the phase field in COMSOL
Yes in COMSOL you can use the level set method I saw a tutorial on it. You can search.
Imran Shah I did some searching but I believe I can't find any tutorial if you can send me the tutorial link I ll appreciate it
Oussama Mebarki I try to search and send. If you can try sharing the COMSOL file, I can do this for you directly. I have 10 years experience in using COMSOL.
First of all, you need to define what exactly you need. For example, let's say you want the average velocity inside the bubble. So, you can take an average of the fluid velocity with the condition of being from the gas phase. You may need to introduce another condition (y
