Abstract
"Mathematical modelling of multiphase flow systems has been a major and persistent challenge over the last decades. Vast attempts to obtain predictive models can be found reported in literature, where major advances can be recognized in recent years, paired to enhancements in computer science and engineering. Notwithstanding, universally valid models with a mechanistic development are far from being achieved. The current status of modelling any multiphase flow system relies on the model order reduction of purely theoretical models. Such reductions and simplifications become the source of deviations in the predictions of the experimentally measured parameters and will constrain the applicability of the models. Hence, when modelling any multiphase flow system, there is a primal need of pairing mathematical modeling and experimental studies, in order to validate the models’ predictive quality, quantifying the deviations and providing a standpoint of the applicability and limitations of the models. In this sense, a successful multiphase flow system model should provide highly accurate local predictions, have a reduced number of possible sources of deviations (i.e., reducing the number of coupled sub-models, nor relying on vast simplifications), and have a high flexibility for being adapted or optimized to different conditions. In this work, it is sought to develop highly predictive, simplified and locally validated mathematical models by applying Computational Fluid Dynamics techniques, paired with other modelling and experimental techniques. Six cases of study are developed: i) Trickle Bed Reactors (TBR), ii) Packed Bed Reactors (PBR), iii) Fluidized Bed Reactors (FBR), iv) Spouted Bed Reactors (SBR), v) Heat transfer systems enhanced by nanofluids, vi) Bubble Column Reactors (BCR)"--Abstract, p. iv
