modelDelayFirstOrder
Delay element, approximated by a first order differential equation
Extends from IBPSA.Fluid.MixingVolumes.MixingVolume.
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.

Changed base class fromModelica.FluidtoIBPSAlibrary. This was done to track the auxiliary species flowmC_flow. -

Fixed bug in assignment of parametersta0. The earlier implementation required temperature to be a state, which is not always the case. -
