Model with powerlaw models
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model demonstrates the use of the 4 PowerLaw models present in the multizone package. The input data is fit so that all models have equivalent output. The pressure difference across the models changes between -1 Pascal and +1 Pascal, which causes air to flow through the orifice.
