  10. Abstract : a continuity wave model is put forward for the dispersion processof liquid - liquid two - phase system, by coupling mass and momentum conservation equations of two - fluid model. the conditions that result in a dispersion choke and the weak instability of a dispersion process are derived from the model. the phenomena of catastrophic inversion and transitional inversion are explained. the effect of drop size distribution on the maximum volume concentration of a emulsion is predicted using the model. according to the theory herein, emulsion inversion is the regime transition of liquid - liquid system due to the instablity of a dispersion process. the effect of drop size distribution on the maximum volume concentration of a liquid - liquid emulsion only occurs in a certain range of weber numbers
