modelMixingVolumeReverseFlow
Test model for mixing volume with flow reversal
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model is the base class to validate the mixing volume with air flowing into and out of the volume and heat, moisture or trace substance added to the volume.
The model volDyn uses a dynamic balance,
whereas the model volSte uses a steady-state balance.
The mass flow rate starts positive and reverses its direction at t=5 seconds.
