.Annex60.Fluid.Delays.DelayFirstOrder

Information

This model approximates a transport delay using a first order differential equations.

The model consists of a mixing volume with two ports. The size of the mixing volume is such that at the nominal mass flow rate m_flow_nominal, the time constant of the volume is equal to the parameter tau.

The heat flux connector is optional, it need not be connnected.

Revisions

• September 14, 2013, by Michael Wetter:
  Renamed V0 to V_nominal to use consistent notation.
• September 24, 2008, by Michael Wetter:
  Changed base class from Modelica.Fluid to Annex60 library. This was done to track the auxiliary species flow mC_flow.
• September 4, 2008, by Michael Wetter:
  Fixed bug in assignment of parameter sta0. The earlier implementation required temperature to be a state, which is not always the case.
• March 17, 2008, by Michael Wetter:
  First implementation.
