Recovery of short‐lived chemical species in a Couette flow reactor

“…This requirement can be fulfilled by using a Couette flow reactor, which was developed to study reaction-diffusion instabilities and pattern formation by groups in Texas (Tam et al, 1988;Tam and Swinney, 1990;Vastano et al, 1990;Ouyang et al, 1991) and in Bordeaux (Ouyang et al, 1989Boissonade, 1990;De Kepper et al, 1990a;Boissonade et al, 1991). The reactor effectively serves as a one-dimensional reaction-diffusion system with a controllable diffusion rate 3 to 5 orders of magnitude larger than that of molecular diffusion.…”
