High-speed flooding flows that occur in swift-flowing river basins and near river bank failures cause damage to building envelopes and other structures due to unsteady hydrodynamic forces. However, there are few studies on the coupled analysis of three-dimensional gas-liquid two-phase flow and elastic structures because of the large computational cost.
In this study, we focus on the Eulerian solution method based on the orthogonal mesh method, which is suitable for massively parallel computation. We propose a coupled analysis method of multiphase flows and structures based on the building-cube method for large-scale coupled analysis of flooding flows and structures.
