Synopsis

A basis for the design of jet-stirred reactors is proposed. A number of reactors for continuous-flow chemical kinetic studies have been constructed on this basis and the fluid flow in the reactor has been examined by means of a hydraulic model. Experiments on dispersion have also been carried out. An analysis of the dispersion achieved by the design leads to simple formulae for the mixing time and the fluid recirculation.

The fluid recirculation in the reactor is found to be close to design predictions. Results of experiments using these reactors for the study of exothermic reactions are presented. In general, the spread of temperature within the reactor (a practical measure of effective mixing with exothermic reactions) has been found to be small and comparable with that obtained with high-speed paddle-stirred reactors.
