Heater / Cooler simulation

1 inlet -> 1 outlet

Governing equations

The exact equations the solver works for a heater / cooler — the same math shown in the app's "Theory" panel, not a black box.

Q = F\,(h_{out} - h_{in})

h_{out} = h_{in} + Q/F \;\Rightarrow\; T_{out} = T(P,h_{out})

Q: duty [W] — heat added (+) or removed (−); this is the knob you set
F: molar flow [mol/s]
h: molar enthalpy [J/mol] — the stream's heat content; Q shifts it and the new temperature follows from the thermo package
T: temperature [K] — an outcome of the enthalpy change, not an input
P: pressure [Pa]

exactly one of: duty [W, +heat/-cool] OR outlet_temperature [K]; optional pressure_drop [Pa]
