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.

[MrPaceTv]

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.)

[thethintrovert]

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?

5:11 why r we making the polygon....for artificial nucleation site

Can I used the same step for sunflower oil heating? .... Tell me please!

[easyhack]

Temperature becomes very high so what to do to get the nucleate range temperature. Please guide

[stevenhopkinsboy]

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.

please provide tutorial video for flow boiling with artificial cavity

[AshishGupta-pwmk]

Weak contribution equation is not clearly visible (comsufed weather is + or -)

[thethintrovert]

Please make a video on 2D axisymmetric model of pool boiling

[santanuborah]

I got this error: Nonlinear solver did not converge.
Maximum number of Newton iterations reached.
Time : 1.8632033400456636
Last time step is not converged.

Can anyone simulate the single bubble on boiling surface in comsol please need help?

[你是就]

This tutorial is great. Could I reprint it to the Chinese website? If you don't mind, please tell me! Thank you so much!

[AshishGupta-pwmk]

I am not able to find phase initialisation option in COMSOL 6.2

[prakhardave.]

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.

[mpoorpanah]

Nice accent, Nice explain, thank you.

[naveenkushwaha]

Very Nice Video., ,,,Can You define variable and parameters and it will be great favor if you provide their text file....

[dariushfaraji]

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 .
