In the first report, the two-dimensional bubble-bubble interaction of wall-sliding bubbles is captured by using Particle Tracking Velocimetry. In this report, trial studies to introduce the bubble-bubble interaction into Eulerian-Lagrangian model have been performed. Firstly, the bubble-bubble interaction force vector is estimated by inverse analysis from the experimental results. The translational motion equation of a bubble is used to derive the interaction force vector. Secondly, two kinds of interaction models are proposed and applied to the numerical simulation. Comparison between the simulated and experimental results revealed that the introduction of the bubble-bubble interaction model enabled to predict much more accurate structure of sliding bubble motion than previous Eulerian-Lagrangian model.
