Pipe Network Unit Operation

Pipe networks are structures built to transport fluids between several supply and demand points. Transmission and distribution of natural gas are examples of services provided by pipeline networks.

In fluid dynamics, pipe network analysis is the analysis of the fluid flow through a hydraulics network, containing several or many interconnected branches. The aim is to determine the flow rates and pressure drops in the individual sections of the network. This is a common problem in hydraulic design.

Model Features

The Pipe Network Unit Operation for DWSIM allows modelling and simulation of pipe networks connected through nodes with multiple sources and sinks. Rigorous compositional fluid property calculations are done by DWSIM Property Packages.

The Pipe Network Unit Operation for DWSIM has the following features:

  • Supports Pipe Segments with Rigorous Heat Transfer calculations, Valves, Pumps, Compressors and Gas-Liquid Separators;
  • Rigorous fluid properties and phase distribution calculated with DWSIM Property Packages
  • Fully-featured Graphical Network Designer
  • Supports Pressure and Mass/Molar/Volumetric Flow specification on endpoints (Sources and Sinks)
