modelTWetBul_TDryBulPhi
Model to test the wet bulb temperature computation
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This examples is a unit test for the wet bulb computation. The model on the top uses the accurate computation of the wet bulb temperature, whereas the model below uses the approximate computation of the wet bulb temperature.
The model contains an assert that validates the model based on a single operating point from Example 17.1 in Ananthanarayanan (2013).
