Sonochemical reactors: scale up aspects

Abstract

The present work deals with the discussion on the engineering aspects of the design of large-scale sonochemical reactors using the solutions of the bubble dynamics equations as well as experimentation with different reactor types and reactions. Design correlations for the collapse pressure and its relation to the cavitational yield have also been given which should assist the designers in the choice of the operating parameters for a desired cavitational effect. Some techniques for the intensification of cavitational activity (with the use of additives) with an aim of reducing the cost of operation have also been discussed. The guidelines for the future work to be carried out to remove the lacunae in the design information with an aim of developing industrial scale efficient sonochemical reactors have also been mentioned.
