Hi
I'm modeling boiling of water inside a tube and I used two wall boiling models, CHF and non equilibrium rpi boiling.
I predicted that when the heat flux is less than critical heat flux, heat transfer coefficient along tube should be the same in both models.
But the heat transfer coefficient that i get from CHF is diffrent from the coefficient that i get from nonequilibrium rpi boiling.

What do you think the reason of this difference is?
