  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

    文摘:以雙流體模型為基礎,通過質量守恆方程和動量守恆方程的耦合,提出了液-液兩相傳質的連續波模型.由該模型得到傳質過程阻塞和傳質過程弱不穩定性產生的條件,計算了液滴尺寸及其分佈對乳化液極大堆砌分的影響,解釋了劇變型乳化逆變和漸變型乳化逆變象.研究結果明,乳化逆變是由於傳質過程的不穩定性而引起的懸浮體型態的改變,隨液滴尺寸多分性的增大,極大堆砌分增大;隨液滴平均尺寸的增大,多分性對極大堆砌分的影響減弱;當韋伯足夠大時,液滴尺寸及其分佈對乳化液極大堆砌分無影響
