| Research Abstract |
A new hybrid model of air phase and bubbles has been developed. Present method is applied to cases of rising bubbles and a rising bubble with an arbitrary number of small bubbles which are smaller than a grid size. Although additional verifications should be carried out, the present method is stable for a mixture condition with large and small bubbles.
