The Modelica Fluid and Media Library for Modeling of Incompressible and Compressible Thermo-Fluid Pipe Networks

Abstract

The new library Modelica_Fluid is a free Modelica package providing components describing zero- and one-dimensional thermo-fluid components, which can be connected in arbitrary networks. The purpose of the library is to provide standard interfaces for thermo-fluid components, demonstrate how to build such models, and include a growing set of models of common use. The component equations are decoupled from the equations to compute the fluid properties, which are provided by the Modelica.Media library through standard interfaces; incompressible and compressible fluids, single or multiple substances, one- and multi-phase fluids can be used, where appropriate. Newly introduced features of the Modelica.Media library are briefly reviewed. After extensive testing by interested users, the library will be included in the Modelica standard library as Modelica.Fluid.
