Information
Model that demonstrates the use of an ideal humidifier.
Both humidifer models are identical, except that one model is configured
as a steady-state model, whereas the other is configured as a dynamic model.
Both humidifiers add water to the medium to track a set-point for the outlet
temperature using adiabatic cooling.
The temperature of the water that is added to the medium is determined by
the parameter T of the humidifier models.

Added flow resistance at the outlet of the humidifier to avoid a numerical derivative, and changed model to use a prescribed mass flow rate. -
