Hi
I am trying to simulate a boiling phenomena with rohsenow correlation. the problem is that i didn't understand what does it mean "HTC" and how to chose the area? Can you help me plzz.

Thank you very much

Hello, Chawki,

I think HTC indicates heat transfer coefficient. by the way what is "rohsenow correlation" ? Thanks.

hi

Yeah i know that, but my problem is how to determine it for a cryogenic liquid (LN2).
The rohsenow correlation is a sort of equation that describe the heat flux between vapor bubbles ans liquid. it was created in 1952 by Rohsenow. It works only for nucleate and film boiling. if you want you can google it

And thanks a lot
