Abstract
A comprehensive review is carried out on the models and correlations for solid/fluid reactions that result from a complex multi-scale physicochemical process. A simulation of this process with CFD requires various complicated submodels and significant computational time, which often makes it undesirable and impractical in many industrial activities requiring a quick solution within a limited time frame, such as new product/process design, feasibility studies, and the evaluation or optimization of the existing processes, etc. In these circumstances, the existing models and correlations developed in the last few decades are of significant relevance and become a useful simulation tool. However, despite the increasing research interests in this area in the last thirty years, there is no comprehensive review available. This paper is thus motivated to review the models developed so far, as well as provide the selection guidance for model and correlations for the specific application to help engineers and researchers choose the most appropriate model for feasible solutions. Therefore, this review is also of practical relevance to professionals who need to perform engineering design or simulation work. The areas needing further development in solid–fluid reaction modelling are also identified and discussed.
Highlights
Heterogeneous solid/fluid reactions have wide applications in chemical and metallurgical processes [1,2]
The reaction rate depends on several parameters, including particle shape, particle size, particle morphology, particle pore structure, chemical kinetics, fluid flow condition, and heat and mass transfer, etc. [8,9,10,11,12,13,14,15,16]
A quick modelling solution with appropriate the same time, this review provides guidance for choosing the correct mode according correlations and empirical equations based on single particle reaction models becomes a desirable option
Summary
Heterogeneous solid/fluid reactions have wide applications in chemical and metallurgical processes [1,2]. Dernbecher et al [20] reviewed CFD simulation correlations and empirical equations based on single particle reaction models becomes a for biomass combustion in fixed beds. New product or to process, or of to perform a quick feasibility or to evaluate or optimize the best our knowledge, this is the study first comprehensive review on the existing processes or operations within a limited time frame, simulation could At be single particle models of the last decades. As such, it fills a precise gap in the literature.
