Bubble-bubble interaction for Lagrangian treatment of multi-component flow

Research output: Contribution to journalArticlepeer-review


Interaction between bubbles for the simple case of a small spherical bubble in the vicinity of a much larger bubble - both rising in stationary liquid - with no mass transfer between liquid and vapor phases, has been studied numerically. The effect of the motion of the larger bubble on the dynamics of the smaller bubble has been determined both for completely spherical, and for spherical cap shaped large bubbles. The complicated motion of the smaller bubble, as it is entrained in the wake of the larger bubble, is clearly seen. This simple model of bubble-bubble interaction - that predicts the essential features observed in experiment - can be used in the computer simulation of individual-particle-tracking method (Lagrangian approach) of two-phase flow analysis.
