＜About Awarded Research＞
The control of particle motions is a problem for the decommissioning of a nuclear power plant, and numerical simulation analysis of a gas-solid-liquid flow is required. The DEM-VOF method, which is combining the discrete element method (DEM) and volume of fluids (VOF), is one of the standard approaches for the gas-solid-liquid coupling simulation. Although this method is well-established, it has a problem is that the number of calculated particles is substantially restricted. In this study, we applied a coarse grain model of the DEM in a gas-solid-liquid flow. Adequacy of the coarse grain model was shown through some verification tests in a rotating cylinder, and the scaling law model could simulate the macroscopic properties of the large-scale particle motions in a gas-solid-liquid flow.

It is my great honor to win this award. I really appreciate Prof. Mikio Sakai for his excellent supervision, and I also thank all members of Sakai-Lab. I will devote myself to improving our research.
