COCO - CAPE-OPEN to CAPE-OPEN simulation environment

Material objects

Thermodynamic standard versions 1.0 and 1.1

All material objects for COFE and TEA support both CAPE-OPEN version 1.0 and CAPE-OPEN version 1.1 standard. More-over, conversions between the two standards are available and automatically applied. Conversions apply to property identifiers, property calculation routines, (two-)phase identifiers and overall calculations. For example, if a CAPE-OPEN version 1.1 property package is loaded into COFE, exporting phases GAS and LIQUID1, a CAPE-OPEN version 1.0 aware unit operation would obtain initial inlet values (pressure, temperature, overall composition) from the material object. If it would need vapor Gibbs free energy, it would call CalcProp on the material object specifying property gibbsFreeEnergy for phase Vapor. The COFE material would translate this into a CalcSinglePhaseProp for gibbsEnergy for phase GAS. The property package sets the values on the material object, the unit operation can obtain then; each using their own version of thermo dynamics.


The following restrictions apply to material objects:
