A method is proposed for measurement of interaction rates of dispersed phase in a continuous flow stirred tank. In the present work a continuous phase stream and two separate dispersed phase streams, one of them containing a tracer and another not, are fed to a tank. The principle of the method makes use of the fact that the distribution of a tracer in a drop population is dependent on the number of interactions of drops, and can be followed by a light transmittance technique.
Validity of the application of the method is examined by the measurement of the light transmissions of an especially prepared suspension liquid whose concentration distribution is initially known. The effects of both impeller speed and volume fraction of dispersed phase on the rates of interactions are compared with those of previous investigators.
