Abstract: Hydrodynamics and mass transfers are discussed both within the dimpled liquid film and along the gas liquid interface between two bubbles, and a model of coalescence is developed, in which the effects of London-van der Waals forces and electric double layer forces are taken into account.The predicted results of the present model match previous experimental data well.

摘要： 对气液二相体系中气泡间凸面状薄液膜内以及气液界面上动量和质量传递行为进行了分析,建立了气泡聚并时间模型,考虑了范德华作用力以及双电层作用力对液膜变薄过程产生的影响.模型值与文献实验值吻合较好.
