Coalescence frequencies in agitated liquid‐liquid systems

Abstract

Abstract An experimental technique is described for estimating the coalescence frequency of droplets in an agitated liquid‐liquid system. Results are presented for dilute aqueous dispersions in toluene. Quantitative estimates of the coalescence frequency are based upon a simple model proposed to describe the coalescence process. The coalescence frequency is shown to increase markedly with increase in impeller speed and to a lesser extent with increase in the dispersed‐phase volume.
