  4. 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-液兩相系中彌散傳質的連續波模型.由該模型得到彌散傳質過程阻塞和彌散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數的影響，解釋了劇變型乳化逆變和漸變型乳化逆變現象.研究結果表明，乳化逆變是由於彌散傳質過程的不穩定性而引起的懸浮體型態的改變，隨液滴尺寸多分散性的增大，極大堆砌分數增大；隨液滴平均尺寸的增大，多分散性對極大堆砌分數的影響減弱；當韋伯數足夠大時，液滴尺寸及其分佈對乳化液極大堆砌分數無影響
