owtp's Introduction

Ordinary Water Thermodynamic Properties

Ordinary Water Thermodynamic Properties (OWTP) is an open-source C library that calculates the thermodynamic properties of ordinary water, which is based on release R7-97 from the International Association for the Properties of Water and Steam (IAPWS R7-97).

Project Goals

Provide a thoroughly-tested, lightweight library that provides conventional steam tables functionality.
Encourage the proliferation of applications that would require the use of conventional steam tables.
Provide relatively easy interop with other languages.

Compilation

Right now, only building with Windows is supported. The next step of this project will be to add Linux support, but this may take some time for me to set up properly because I don't have a Linux box and I'm new to Linux.

To compile the code into a shared library:

Clone the repo to a directory.
Cmake is the build generator, so the following commands should allow you to build the library.

mkdir build

cmake -Bbuild -H. -DCMAKE_CONFIGURATION_TYPES=Release

cmake --build build --config Release

This should build a shared library named OWTP.dll in the following folder: ./build/src/bin/

Region 4: Implement and Test x(h,s)

Implement and test x(h,s) starting on page 32 of the following document:

Supp-phs3-2014.pdf

These will be tested against values generated from x(P,T).

Region 3: Implement and Test Auxiliary Equations for Properties(T,P) for the Subregions Near Critical Point

Implement and test the auxiliary equations Properties(T,P) for the subregions very close to the critical point.

These will be implemented by calculating v(T,P) and inputting the result into Properties(v,T).

These will be tested using the same numbers used to test Properties(v, T).

Remake C++ Tests into C#

I'm more familiar with the c# unit testing framework, so I should be using that.

Region 2: Implement and Test Properties(P, h)

Implement and test the appropriate properties as functions of pressure and specific enthalpy.

#3 need to be finished before this is started.

This will be implemented by:

calculating temperature as a function of pressure and specific enthalpy
calculating the other properties as functions of temperature and pressure

This will be tested by using the values found in table 15 on page 17 of the attached document.

Region 2: Implement and Test Properties(P, s)
