modelValveRealGas_L1

Valve for real gas models without phase change with replaceable flow models

Extends from ClaRa.Basics.Icons.ComplexityLevel (Displays the complexity level inside model icon ), TransiEnt.Basics.Icons.Valve.

Information

1. Purpose of model

This model represents a valve for real gases. It is a modified version of the model ClaRa.Components.VolumesValvesFittings.Valves.ValveVLE_L1 from ClaRa version 1.2.1. The model is documented there and here only the changes are described.

2. Level of detail, physical effects considered, and physical insight

The two-phase region is deactivated.

3. Limits of validity

Only valid for real gases without phase change.

4. Interfaces

gasportIn: inlet for real gas

gasportOut: outlet for real gas

opening:in: realinput
