The effect of the draft tube geometry on mixing in a reactor with an internal circulation loop - A CFD simulation

Popis výsledku v původním jazyce

The main topic of this paper is to describe the effect of geometrical parameters on mixing time in a reactor with an internal circulation loop. The design of the draft tube inside the reactor is an important geometric parameter and has a big influence ontwo phase hydrodynamics as well as on mass transfer in the reactor. In thefirstsection,the validation of theselected mathematicalmodel iscarried out. The results ofexperimental measurements (liquid velocity and gas hold-up) obtained on the laboratory scale reactor are compared with the CFD simulations. The CFD simulation (bubbly flow and mass transfer models) was made using COMSOL Multiphysics 3.5a. The results of the numerical simulation are in good agreement with the experimental data. In the secondsection, the study of mixing in the reactor is described with the new geometry of the draft tube. The standard experimental techniques for testing mixing processes are quite problematic because common tracers (soluble salts) have signific
