A COMPUTER-AIDED SYSTEM FOR GENERATION OF PROBLEM SPECIFIC PROCESS MODELS

A methodology for automatic generation of problem specific process mod els to be used in simulation related to process design and operation i s presented. The methodology is essentially based on information relat ed to setting up control shells, physical description of the interior of the control shells, and, specifications of the various types of int eractions between the control shells and the surroundings. From the de scription of the control shell, the computer aided system generates th e problem specific model equations from a reference model which contai ns all the necessary terms for modelling a chemical process. The algor ithmic aspects of the methodology are highlighted and two non-trivial applications are presented.
