fluid choke
1.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.
