Hello,

I am trying to simulate a case of flow boiling inside pipe using RPI Non-equilibrium boiling model. In mass transfer, ther is one term called as liquid/vapor-interface transfer coefficient. I tried to find the meaning of that in Fluent theory guide. But, couldn't find it anywhere. Can anyone please help me to define its meaning in governing equation?

Checking, they are mentioned, but not necessarily in the boiling model section. However, it's also recommended to leave them alone.

And found it (with help),  https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v231/en/flu_th/flu_th_sec_mp_evap_cond.html  just below equation 14-616.

The above link is not opening. It says, I need to provide some customer ID if I am outside the United states. Can you please share readble pdf or something?

Click on Help in Fluent. Then paste the link into the browser that opens. The documentation isn't public domain, but as a user you're able to access it: the solvers add a token/cookie/biscuit to the browser session.

I also clicked on Fluent help which lead me to browser. Pasted this link and it again leads me to Ansys Customer Support Space Registration Form where it is asking me for customer number (which I don't have). I use my ANSYS in my institute HPC. I don't have my personal licence number or customer ID.

Weird, it works for everyone else.

Can you please share screenshots of the webpage where relevant part is given ? 

[Rob]

Unfortunately not, it's one of the oddities of working on here. I can't share anything that's not "public" and as posts can be seen without logging in I can't add any documentation: and that's before the copywrite bit triggers.
