This model with lumped volumes describes turbulent flow. The flow is defined by the equation:



where

		:	Mass flow rate
		:	Fluid density
		:	Discharge coefficient
A		:	Opening area
		:	Pressure difference between ports a and b

Implementation

The flow equation is linearized for pressure differences near zero to increase numerical stability.

Limitations

This model is only valid for turbulent flow. No checks are made if it is physically possible that the flow through the component actually is turbulent.
