Dynamic Behavior Of An Agitated 2-Phase Reactor With Dynamic Variations In Drop Diameter .1. Numerical Simulations

Abstract A model assuming infinite drop coalescence and break-up rates was used to study the dynamic behaviour of chemically reacting liquid-liquid dispersions with simultaneous interphase heat and mass transfer in continuous reactors. The investigation has shown that, in some cases, it is important to take into account dynamic variations in interfacial area for proper description of reactor behaviour. It was found that in most cases in which there is a dynamic dependence of drop size on phase composition, phase temperature and/or impeller speed, oscillatory behaviour of concentration and temperature results that can bring the reactor into undesirable situations. The oscilliatory character of the transient response is a result of the dynamic lag between drop size and system variables.
