Models for Dynamic Applications

This chapter covers aspects of the dynamic modelling and simulation of several complex operations that include a controlled blending tank, a direct methanol fuel cell that incorporates a multiscale model, a fluidised bed reactor, a standard chemical reactor and finally a polymerisation reactor. These models help illustrate aspects of model formulation, the generation of the underlying assumptions about the systems, the degrees of freedom analysis and finally the solution and simulation of the models subject to changes in a variety of inputs. It is shown how an integrated system such as ICAS-MoT can be applied to formulate, analyse and solve these dynamic problems and how in the case of the fuel cell problem the model consists of coupledmeso and micro scale models. It is shown how data flows are handled between the models and how the solution is obtained within the modelling environment.
