| Research Abstract |
A computational method has been developed to predict the transportation of large-scale objects, such as rocks, ships and debris of buildings, due to the 3D free-surface flows caused by flood and Tsunami. For this purpose, a new multiphase model was proposed to deal with gas, liquid and solid phases. In addition, the proposed model was implemented in a computational scheme based on high-performance computing algorithms and the method was verified by the comparisons with experimental results. In particular, 1) the development of 3D models and the introduction of some parallel computation methods were performed, and 2) multiple experiments were conducted regarding the transportation of solid objects by free surface flows.
