Numerical and experimental investigations on bubbly channel flows through closely arranged cylinders have been carried out. This paper concerns with the results of the three-phase simulation using Eulerian-Lagragian model in which the cylinder-bubble interaction model is taken into account. The results show that rising velocity of bubbles decreases due to the bouncing of the bubbles at the cylinder surface, and the characteristic scale of the liquid flow is altered with the arrangement patterns of the cylinders.
