coolprop's Introduction

Welcome to CoolProp

CoolProp is a thermophysical property database and wrappers for a selection of programming environments. It offers similar functionality to REFPROP, but CoolProp is open-source and free. It was originally developed by Ian Bell, at the time a post-doc at the University of Liege, in Liege, Belgium.

CoolProp has flexible licensing terms: Commercial - ok! Academic? - ok!
For Python, get the latest release via pip install coolprop

@jowr - check it out!

This is based on SWIG since I can't get xdress+cython working so far on windows:

import CoolProp

for backend,fluid in [("REFPROP","Ethane&Propane"), ("HEOS","Ethane&Propane")]:
    S = CoolProp.AbstractState_factory(backend, fluid)
    S.set_mole_fractions([0.5,0.5])
    S.update(CoolProp.PT_INPUTS, 1e5, 300)
    print S.rhomolar()

Configure buildbot as build engine for all platforms - going to be great solution

See http://docs.buildbot.net/current/tutorial/firstrun.html

So nice that it is python based. Will be easy to configure, set up, upload as we like, etc.

[CLOSED] High level API for CoolProp

Issue by ibell
Monday May 05, 2014 at 21:52 GMT
Originally opened as CoolProp/CoolProp-museum#5

@jowr, @squoilin etc.

I have fixed and added almost all the flash routines for pure and pseudo-pure fluids - see the v5 branch. The first set of rough consistency tests all pass for REFPROP. CoolProp still has a few cases that fail, and I need to add a few more flashes yet. I'm currently revisiting the high-level interface, and I don't know what the best way to handle the high level interface is. A couple of options:

double r0 = PropsSI("Dmass","T",298,"P",101325,"REFPROP-Propane[0.5],Ethane[0.5]");
std::vector<double> z(2,0.5);
double r1 = PropsSI("Dmass","T",298,"P",101325,"REFPROP-Propane,Ethane", z);
// and/or
double r2 = PropsSIZ("Dmass","T",298,"P",101325,"REFPROP-Propane,Ethane", z);

Basically the options are some combination of
a) Encode the mole fractions in the string (definitely will be supported), need to decide on the delimiters though. Perhaps we just stick with what we did before. I like '-' between backend and fluids, but some fluids ('n-Propane', etc.) have a '-' in the name. Or we could use "::" to get something like "REFPROP::Water". Would be kind of like C++, which has some appeal. I am less sure about the delimiters for mole fractions.
b) Overload (?) the PropsSI function with a form where you pass molar(!) fractions as the last parameter
c) Another function name entirely that takes mole fractions

Fit "melting" line

The "end" of the equation of state in the solid/liquid domain can be approximated by seeing where the EOS starts having wonky behavior, some sort of deviation from the bulk behavior perhaps as a rough estimation of the melting line. Maybe finding the point where dpdrho is negative, or something like that.

Or at least this method could be used in order to yield sensible limits for the equation of state.

[Tabular] Warn about tabular folder size

Something wrong on linux - seg faults

The Fluid Library does not seem to be getting loaded. It's not clear why, nor what the problem is. Need to do more debugging.

Don't evaluate NonAnalytic terms if contribution is less than numerical precision

We can avoid the slowdowns caused by the non-analytic derivative by determining how far away from the critical point you need to be for its contribution to be less than numerical precision, and only calculating when it is above numerical precision. If contribution is less than numerical precision it will literally disappear.

coolprop.org links don't redirect

Hey @Rod-Persky I noticed a couple of problems with coolprop.org some time back but never emailed you.

It seems that any links outside of the website (sourceforge downloads for instance), are not getting redirected and they take me to a blank page. Any idea why that might be the case?

Also, in the browser web address, its always coolprop.org even as you navigate around the site. This also isn't ideal, any way we can change it?

calculate derivatives of residual helmholtz in parallel

Can re-use much of the derivative information about the terms - perhaps cache intermediate parts of the calculations for delta^d_k*tau^t_ketc. This term repeats in all of the derivatives. See derivative derivations for generalized power/exponential term.

Or allow user to select which derivatives are calculated in one shot, allowing for as much re-use as possible. At least the common terms could be cached.

Try to avoid any conditionals, they slow down the code and cause branch prediction failures.

Select partial derivative based on string

Issue by ibell
Tuesday May 06, 2014 at 06:27 GMT
Originally opened as CoolProp/CoolProp-museum#6

I propose, at least for first partial derivatives, something like

"d(X)/d(Y)|Z"

which will call the correct partial derivative using the generic routine. It's not quite as nice as hard coding variables for each derivative, but then there are 6_5_4 = 120 possible triples of the 6 thermodynamic variables T,D,S,H,U,P

And for second partials, we could do something like

"d2(X)/d2(Y)|Z"

Higher order partials

Originally opened as CoolProp/CoolProp-museum#7

So what do we do about the API for higher order partial derivatives? It starts to get really messy. Ideally we could support up to third partials, but second partials are already nasty enough.

See #6 for first partials.

We can express all second partials in terms of tau and delta, after a bit of math. In that way we could use a generic routine that we could easily test.

I added an external dependency on the Eigen framewrork and started using it in MatrixMath and PolyMath. However, we still need to convert our linear algebra solvers to make use of Eigen's features.

Use Google Test for tests

There are a few tests in the code (SpeedTest.cpp, Tests.cpp) it might be easy to split these out into their own directory Tests/ and then build them with gtest (which is easy to maintain)

Reminder for a CMake file to run the example code

Truncation/EOS error and accuracy

Hello

I am interested in evaluating a few derivatives using Coolprop, some of which are not available by default, and I wanted to know how far I can go, particularly on MATLAB, without loss of precision by truncation error or EOS inaccuracy. I am currently using Richardson extrapolation to obtain precise derivatives as I am working near the critical point, and, theoretically, I can get infinitely precise first order derivatives as long as my EOS can give me accurate results for small variations in state functions.

Let a = abs(enthalpy(p, T) - enthalpy(p + dp, T)), I found that for dp ~ 1e-10, a = 0, so the derivative cannot be evaluated. I would like to know if there are other errors which would limit even more the interval from which I can evaluate those functions.

    path = os.path.dirname(path)

    if os.path.exists(os.path.join(path, ".JSON_done")):

Originally opened as CoolProp/CoolProp-museum#18

The solver loops simply terminate when the max amount of iterations is reached. This seems to be undesired. There is an error message that will never be printed, the exception will never be thrown.

double Newton(...)
{
...
    while ((iter < 2 || fabs(fval) > ftol) && iter < maxiter)
    {
...
        if (iter>maxiter)
        {
            errstring= "reached maximum number of iterations";
            throw SolutionError(format("Newton reached maximum number of iterations"));
        }
        iter=iter+1;
    }
    return x;
}

The while loop terminates 2 iterations before the exception is thrown. What is the intended behaviour?

Automated builds

We would like automated builds for distribution as well. Travis builds are fine for testing and for Linux machines.

However, we would like to support the Windows users with some binaries and include Mac as well.

Let us collect notes and ideas here.

For now, we favour a cron job running on a Mac to launch virtual Windows and to make nightly builds.
