Thank you very informative and seems to work on comsol 5.5 by replicating the steps. One change is Radiation is added separately and than coupled in multiphysics interface with the fulid (when adding equation for the weak form it turns yellow test(p) which denotes unknown variable p which is probably pulled later from pressure(perhaps) so doesn't create any issue.)
I got this error: Nonlinear solver did not converge. Maximum number of Newton iterations reached. Time : 1.8632033400456636 Last time step is not converged.
Hi thanks for sharing this video. I would say, the equation of mdot and delta which located in variable definition are invisible. I couldn't run it due to these two variables. I'm a student, please guide me or share the total equations of them .
it is the convective boiling which comes before the nucleate boiling but here most of the parameters that have been added by the presenter belongs to nucleate boiling. it is my from my view i can be wrong.
This is a very good tutorial. Thanks. I want to extend it to 3D by simply building corresponding geometry and setting corresponding physics interfaces and conditions. But it didn't work. There was an error like "can't find consistent initial value". Can someone help me with this problem?

Today I succeeded in simulating BHT using COMSOL all because of this video and Christina Madam. I am obliged to you, ma'am. Thanks for the effort.
Can you guide me please how did you do that?
Thank you for this video. This really helped me a lot. The speaker here has now moved to Northop Grumman noq..
I do not find initial interface in phase fields in the latest comsol model so what to do?
I am not able to find phase initialisation option in COMSOL 6.2
i love your voice so much
5:11 why r we making the polygon....for artificial nucleation site
please provide tutorial video for flow boiling with artificial cavity
In the parameters, you use "T" in order to evaluate other variables such as "rho_v" however you don't have a definition for 'T" in the text documents.
T is the temperature calculated by the heat transfer in fluids node
quite wonderful
Excellent video
Please make a video on 2D axisymmetric model of pool boiling
Can I used the same step for sunflower oil heating? .... Tell me please!
Can anyone simulate the single bubble on boiling surface in comsol please need help?
Weak contribution equation is not clearly visible (comsufed weather is + or -)
Nice accent, Nice explain, thank you.

Awesome it is,... please upload more tutorials on real life exciting phenomenons 😀
Just trying to figure out how many BTU I need to get 40gals to boil in 8.5 minutes in a 30X30 22' deep square aluminum vessel.
results and discusssion 24:04
This tutorial is great. Could I reprint it to the Chinese website? If you don't mind, please tell me! Thank you so much!
Very Nice Video. ,,,,Can You define variable and parameters and it will be great favor if you provide their text file....

il y a 1 mois
can you tell me which version of comsol you use???? please
how to create txt files please.
can I perform with comsol 5.2?
That was a good tutorial
I tried simulating the same without creating the cavities, but it didn't work.
Can you help ?
pare! is this not related to your work?
is it showing nucleate boiling or film boiling...pls reply
it is the convective boiling which comes before the nucleate boiling but here most of the parameters that have been added by the presenter belongs to nucleate boiling. it is my from my view i can be wrong.

Hi, did you find the solution to your problem?
Not yet.
@@刘远洋-c2q hve you found the solution to this problem. We can discuss
