✦ Synopsis

This work deals with the experimental study of the circumferential mixing in the Taylor vortex flow between coaxial cylinders. Bach pair of vortices is considered as a closed chemical reactor and the residence time distribution in this reactor is determined by an electrochemical method. The tanks-in-series model with recirculation is applied to describe the flow in the vortex reactor; the circumferential mixing is characterized by the number of tanks in series and by the mixing time. Experiments werecarried out with onephase flow and with two-phase liquid-liquid flow. It is shown that stirring due to the liquid droplets increases the circumferential mixing.
