The Matlab CAPE-OPEN Unit Operation is a unit operation implementation for which the calculations can be entered in Matlab.
To get started with the Matlab CAPE-OPEN unit operation, start your CAPE-OPEN capable simulation environment. Insert a Matlab CAPE-OPEN unit operation. Edit a unit operation. Define feed and product ports. Go back to the simulation environment and connect streams to the ports.
Now edit the unit operation again. On the Matlab tab, you can enter the Matlab calculation script. This script
can obtain feed properties using the
getFeedProp function. It can then do calculations, using thermo-dynamic
calculations that are based on the underlying thermodynamic system of the simulation environment the unit operation
is running in. It must specify all the product streams using
setProduct, that takes composition and
flow as well as two other properties required to specify the thermodynamic phase equilibrium.
A very simple example script would look like:
f1=getFeedProp(1,'flow') f2=getFeedProp(2,'flow') h1=getFeedProp(1,'enthalpy') h2=getFeedProp(2,'enthalpy') p1=getFeedProp(1,'pressure') p2=getFeedProp(2,'pressure') p=min(p1,p2) f=f1+f2 h=(h1*f1+h2*f2)/f totF=sum(f) setProduct(1,totF,f/totF,'pressure',p,'enthalpy',h)
The Matab unit operation will function in CAPE-OPEN compliant simulation environments that support version 1.1 thermodynamics or version 1.0 thermodynamics (requires Matlab 7.1+). It has been tested in COCO simulator, SciSci ProII, AspenPlus, Honeywell Unisim Design and other simulators.
Matlab version 5.3 (32-bit) or higher, or Matlab version 7.1 (64-bit) or higher must be installed and running at your system. The Matlab CAPE-OPEN unit operation has been tested with Matlab versions 5.3, 6.1, 7.7, 7.8, 7.9, 7.10, 7.11, 7.12, 7.13, 7.14, 8.0, 8.1, 8.2, 8.3, 8.4, 8.5, 8.6, 9.0, 9.1, 9.2 and 9.3.
