modelTestGasGridHamburgVarGCV

High pressure gas grid of Hamburg with variable gross calorific value at consumption side

Extends from TransiEnt.Basics.Icons.Checkmodel (Icon for check models).

Information

1. Purpose of model

Tester for open-loop high pressure gas ring grid of Hamburg with variable gas composition calculation. The gas has constant composition but the all components use the equations for variable composition.

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

The methodology is described in [1].
