APPLICABILITY OF PREDICTION METHOD FOR MULTIPHASE-FLOWS (3D MICS) TO FLOOD FLOWS AMONG MULTIPLE BUILDINGS

Abstract

It is important to evaluate the detailed inundation process of flood flows in the area where multiple buildings closely exist. In this study, a small-scale experimental model is used to measure the initial stage of the unsteady free-surface flows which extend among impermeable boxes that simulate the arrangement of buildings. The experimental results are numerically predicted with a 3D computational method for multiphase flows, 3D MICS, which enables us to deal with the front area of free-surface flows without additional manipulation. As a result of computations, it has been shown that the unsteady process of flood flows are reasonably predicted with 3D MICS.
