Many engineering disciplines are turning to extend the range of their modelling capabilities, such as the modelling of chemical processes which are generally modeled through monoscale approaches while not adequate, they satisfy a useful role in product-process design. Use of a multi-dimension and multi-scale model-based approach is, however, beneficial and necessary in product process development of special materials and/or chemical products. Higher levels of details and accuracy involving a wide spectrum of partial and temporal scales can be achieved in this way. A flexible computed-aided framework for model generation, analysis, solution and implementation will allow the development and application of the desired model-based approach for product-centric process design/analysis. This can be achieved through the integration of a model generating system (ModDev), and a modelling tool (Mot) for model translation, analysis and solution.
ModDev is a computer aided tool that is able to generate and develop model equations for chemical engineering processes while MoT is another computer aided tool able to make the translation, analysis and solution of the generated model equations. Moreover, MoT is able to generate model objects that could be used in other computational tools such as external software (i.e. EXCEL), simulation engines (Icassim and Dynsim available in ICAS software) or even external simulators (ProSim, etc). The combination of ModDev, MoT and ICAS (or any other simulators) permits that different models and/or process configurations can be simulated very easily and quickly, reducing time and human resources for model development and solution. But, why do we need to use ModDev and MoT together as a new modelling framework? Because through their interaction, model equations for a specific equipment, process or operation would be developed by ModDev; and then translated, analyzed and solved through MoT with almost zero programming effort with the multiscale modelling approach embedded in the final model equation.
The objective of this paper is to present the modelling framework, and through it, the synergy between ModDev and MoT; together with new modelling features such as multiscale modelling and models needed for specific product-centric process design that are usually not found in commercial simulators. Application of these modelling tools will be highlighted through two case studies-one involving a fuel cell model and the other involving the controlled release of active ingredients from micro-capsules. In both cases, the multiscale issues handled by the modelling tools will be illustrated.
