Final Report Summary - MODELICAPROP (Modelica Standard Library for Thermodynamic and Transport Properties)

Executive Summary:
In this project a Modelica library for multi-phase multi-component fluids has been developed together with an external C/C++ Modelica property interface with back ends to CAPE-OPEN, RefProp and FluidProp. The framework also contains a Modelica library for distillation processes for verification and testing of the media interface design. The availability of properties for steam and flue gases initiated the use of Modelica in the power industry, where it today is a well-established technology with several commercial and open source libraries available. High quality fluid properties are laborious to produce and their non-availability is therefore a typical blocking argument for the use of a certain tool or technology. In this project we have also developed requirement specification of an open-source framework for multi-phase multi-component thermo properties in Modelica. The goal is to have a standardized interface to multi-component multi-phase fluids with access to external property packages in Modelica. This will make it easier to develop models for e.g. the process industry. The library uses a model based interface and implications of such a design are analyzed and compared with the traditional function based interface.

Project Context and Objectives:
In this project a Modelica library for multi-phase multi-component fluids has been developed together with an external C/C++ Modelica property interface with back ends to CAPE-OPEN, RefProp and FluidProp. The framework also contains a Modelica library for distillation processes for verification and testing of the media interface design
Main objectives of the ModelicaProp project are:
• Extend the scope of the current Modelica.Media interface to multi-component multi-phase fluids
• Make external thermodynamic properties available in Modelica.Media through a unified external interface

Project Results:
See attached document

Potential Impact:
The final results are:
• New Modelica multi-component multi-phase media library
• New Modelica-C thermodynamic-properties interface
• Interface to NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP). It implements the developed generic Modelica-C interface
• Interface to software exposing the CAPE-OPEN interface. It implements the developed generic Modelica-C interface.
• Distillation Modelica library. Used to evaluate use cases.
• A technical report which describes the proposed interface and the motivation for the design decisions.
The tool-independent Modelica technology has demonstrated that model-based systems engineering processes can increase the efficiency of design processes. It is our hope that the model library developed in this project will initiate a similar development in the aerospace industry as those that have already taken place in the automotive and power industries, where innovative companies have built their innovation processes for systems engineering around the Modelica technology.
One should note in this context that Modelica is a technology that has been developed mostly in Europe, and European companies, in particular SMEs, have developed and exploit most of the intellectual property related to Modelica.
A paper "MultiComponentMultiPhase – a framework for thermodynamic properties in Modelica" was presented at the 11th international Modelica Conference in Versailles in September 2015. The result of the project in form of Modelica Interface Library is publically available at https://github.com/jwindahlModelon/MultiPhaseMixtureMedia.Results of this project have also been used in Modelon's Vapor Cycle Library product.
