Exchanger model without heat transfer coefficient calculation, for
two phases flow in tubes
The model is for a tube heat exchanger, that can have several
passes and extended surface, in an undefined external flowing
media. We need to specify the global U, as it is impossible its
calculation. We define also the inner media, and the external media
Cp, inlet temperature, and outlet temperature or mass flow rate.
As an alternative it is also possible to use a fixed exchanged
power, or a fixed temperature for the tubes external surface.
As two phases are coexisting along the exchanger a straight
LMTD method is used.
