NUMERICAL-CALCULATION OF SCALE-UP EFFECTS OF PRESSURE FIELDS IN SONOCHEMICAL REACTORS - HOMOGENEOUS PHASE

Over the last few years a large number of chemists and engineers worki ng in synthesis and materials processing are interested in application s of ultrasound. Ultrasound may lead to higher yields, higher selectiv ities or even new products. The development of fundamentals for the de sign of sonochemical reactors is still in the beginning. In this paper linear effects of sound fields in sonochemical reactors in a homogene ous phase are investigated. Scale-up effects in some types of reactors have been calculated, especially the energy density distribution with in the reactor. From this distribution the probabilities of the genera tion of cavitation bubbles can be calculated.
