Tank jacket heat transfer coefficients

[BobStafford]

Long time stalker, first time poster!

I'm compiling open literature design methods to estimate heat transfer coefficients for three types of vessel jackets: annular (plain), half-pipe and dimple jackets. I've had some good success for single-phase flow, but have run aground when it comes to 2-phase flow, principally saturated steam vapour which would condense in the jacket, and saturated liquid ammonia which would boil during transit through the jackets. Regarding the boiling ammonia, I initially thought a Chen correlation would suffice, but from what I can see Chen is only recommended for vertical flow within a circular pipe.

Is anyone aware of any design method/s for two-phase heat transfer in the three jacket designs mentioned?

Thanks in advance.
