CAPE-OPEN

The redlich-kister model for liquid thermophysical properties can be implemented similar to enthalpy ideal+excess model with ideal coming for molar or mass mixing rule. The empricial parameters can be supplied implemented in a way similar to NRTL or other models requiring parameters for computing mi...

e-NRTL although a better representation is not a requirement. actually, NRTL should be sufficient for modeling purposes for the type of analysis i am after. It will be great if the simple or temperature corrected Redlich-Kister mixing model can be incorporated as a selectable option for main thermop...

The liquid-vapor and liquid-liquid phase equilibria (no solids in my application at the moment) can be calculated from Antoine equation and activity coefficient model such as NRTL or e-NRTL respectively. The Redlich-Kister equation is only to utilize excess property concept for mixture properties of...

The basic Redlich-Kister equation is presented in Eq.11 of the link shared earlier in the second post of this thread. The mixing model involves summation of pure component properties multiplied by their respective molar fraction and the excess property calculated by Redlich-Kister expansion is added...

I do not understand why equation of state and derivatives are involved when all i want to accomplish is provide a single equation (one each for the five properties of interest) that predicts the properties of mixtures by using the excess property concept. A big simplification in my case is that ther...

Thanks for your insightful reply summarizing how CAPE-OPEN property packages work in the background and how the CAPE-OPEN specs can be used to achieve what i want. However, i am not experienced in VB or C++ and therefore can't write a full COM object to fulfill the requirements of TEA. The easiest r...

As you mentioned, i am looking for a way to customize calculation of a few important properties using subroutines. To be more specific, using Redlich-Keister model with temperature correction to estimate mixture properties (density, viscosity, specific heat, thermal conductivity and electrical condu...

Can anybody advise whether there is a CAPE-OPEN thermo property package in which custom models can be defined using MATLAB/Python/Excel? My application is to design process components involving novel ionic liquids and water. I checked “configure TEA” as a potential CAPE-OPEN thermo property package ...
