The air-water bubbly two-phase flows containing many micro-bubbles of 10-100 microns in diameter can be utilized various advanced science and engineering fields. However, a fluid-dynamic structure of air-water bubbly flow with micro-scale bubbles is not known until today. As for the computational fluid dynamic approaches, in general, it is difficult to distinguish two interfaces in one computational cell for any Eulerian computational procedures with the front capturing and volume tracking method. This paper describes that a micro-bubble interaction model has been developed using an image processing technique combined with the Eulerian computational method, so-called MARS (Multi-interface Advection and Reconstruction Solver) developed by one of the authors.
