文摘:以双流体模型为基础，通过质量守恒方程和动量守恒方程的耦合，提出了液-液两相系中弥散传质的连续波模型.由该模型得到弥散传质过程阻塞和弥散传质过程弱不稳定性产生的条件，计算了液滴尺寸及其分布对乳化液极大堆砌分数的影响，解释了剧变型乳化逆变和渐变型乳化逆变现象.研究结果表明，乳化逆变是由于弥散传质过程的不稳定性而引起的悬浮体型态的改变，随液滴尺寸多分散性的增大，极大堆砌分数增大；随液滴平均尺寸的增大，多分散性对极大堆砌分数的影响减弱；当韦伯数足够大时，液滴尺寸及其分布对乳化液极大堆砌分数无影响 - In this paper , based on summarizing previous numerical studies on wave transformations , several works are documented : based on the mass conservation equation and euler ' s equation , the extended form of boussinesq equations is derived by using the velocity at an arbitrary water depth as the independent variable , and several terms are added into governing equations to model the effects of bottom friction , wave breaking and subgrid turbulent mixing
