REFPROP CAPE-OPEN Property Package Manager

REFPROP

REFPROP is a program that uses equations for the thermodynamic and transport properties to calculate the state points of the fluid or mixture. These equations are the most accurate equations available world wide. Their high accuracy is obtained through many coefficients in the equations, and thus the calculation speed will be slower than other equations such as Peng-Robinson cubic equations. The equations are generally valid over the entire vapor and liquid regions of the fluid, including super-critical states; the upper temperature limit is usually near the point of decomposition of the fluid, and the upper pressure (or density) limit is defined by the melting line of the substance.

The REFPROP program is authored, maintained and distributed by the National Institute of Standards and Technology (NIST). The REFPROP program is available for a small fee from the NIST web site (http://www.nist.gov/srd/nist23.cfm).

REFPROP CAPE-OPEN

If you have REFPROP version 8.0 or higher installed at your computer, and you would like to use REFPROP thermodynamic in CAPE-OPEN compliant simulation environments, then the REFPROP CAPE-OPEN Property Package Manager is what you are looking for.

The REFPROP CAPE-OPEN Property Package Manager allows creation of Property Packages using a simple graphical front end:

Here, you can create and maintain Property Packages. A Property Package is a collection of compounds and calculation methods that you want to use in your simulation. The REFPROP CAPE-OPEN Property Package Manager provides a simple user interface to configure Property Packages:

Any of the REFPROP Fluid files (*.fld) that are available on your system can be used in a REFPROP Property Package.

After creation of the Property Package, you can load and use your Property Package in a CAPE-OPEN compliant simulation environment. This example shows how to load a REFPROP CAPE-OPEN Property Package in the COFE simulation environment:

After selecting the REFPROP Property Package Manager, a Property Package can be selected:

Requirements

The REFPROP CAPE-OPEN Property Package Manager does not include REFPROP itself; REFPROP can be obtained from the NIST web site.

The REFPROP CAPE-OPEN Property Package Manager requires REFPROP version 8.0 or higher to be installed at your system. For the x64 version of the REFPROP CAPE-OPEN Property Package Manager, REFPRP64.dll must be present as part of the REFPROP installation; this DLL will automatically be installed for REFPROP version 9.1 or higher.

The REFPROP CAPE-OPEN Property Package Manager is a COM object that will run in Windows environments.

To use the REFPROP CAPE-OPEN Property Package Manager, a CAPE-OPEN version 1.0 or version 1.1 compliant simulation package is required. For example COCO and many others.

Availability

The REFPROP CAPE-OPEN Property Package Manager is available from the Downloads page as a Windows installer package. This is a 7-day free trial. After the trial period, if you want to continue to use the REFPROP CAPE-OPEN Property Package Manager, registration is required.

For registration, a license fee must be paid. Licensing is on a per-person basis (and can be used on multiple computers). The license fee for a perpetual license is € 150,- (if you do not have a VAT number, and if you are outside the European union or inside Spain, VAT of 21% is applicable).

Before registering the REFPROP CAPE-OPEN Property Package Manager, please download and install the trial version to ensure the software does what you expect.
