International Journal of Chemical Reactor Engineering, 2012 Abstract The continuous operation of a stirred tank reactor for styrene polymerization was modeled. The proposed approach consists of an iterative procedure between two modules that considers the fluid-dynamics and kinetics respectively. The kinetic module considers a complex kinetic mechanism and is used to predict the time evolution of global ...

Computational fluid dynamics modelling of residence times in vegetated stormwater ponds [PDF]
Proceedings of the Institution of Civil Engineers - Water Management, 2018 Experimental data characterising dispersion within Typha latifolia were previously collected in a laboratory setting. This mixing characterisation was combined with previously proposed computational fluid dynamics modelling approaches to predict residence time distributions for vegetated stormwater treatment pond layouts (including a wetland) derived ...

Introduction of novel characteristic time quantities to describe chemical reactors
Chemical Engineering Journal Advances, 2023 The Mean Residence Time is a quantity which is used very often to characterise chemical reactors. This quantity can be calculated using the Residence Time Distribution of a specific, continuous reactor and assuming closed-closed boundary conditions. Many
