E. coli Inactivation Kinetics Modeling in a Taylor-Couette UV Disinfection Reactor

Figure 7

At 300 rpm, (a) radial velocity vectors of the 16 counterrotating toroidal vortices formed along the reactor length. (b) Some intercalated, red, jet-like flow structures emerging at high radial velocities from the inner (rotating) wall and going to the outer (fixed) wall. A mass transfer barrier between adjacent vortices formed.
