.SiemensPower.Components.Pipes.TubeWithoutWall

Information

This tube model comes with a detailed energy, but integrated momentum and mass balance. See pdf documentation for details of the integration of the hydrodynamic equations. Both heat transfer and friction pressure drop can be selected from a set of correlations.

Model restrictions

• Mass accelaration pressure drop is not considered
• The tube comes without wall. It is not possibel to connect external heating
• dynamic mass balance has no effect if medium is incompressible
