About awarded research

Title of presentation: Application of DEM-VOF simulation to a large-scale system
Abstract of presentation:
DEM-VOF, where solid particles are modeled by DEM and the gas-liquid interface is modeled by VOF, is widely used for solid-gas-liquid three-phase flow simulations. In our laboratory, we have introduced a coarse-grained model to reduce the number of particles and a refined grid model to allow flexible setting of the grid size for fluid simulation, which enables large-scale solid-gas-liquid three-phase flow simulations. In this study, we also applied an implicit method for the fluid drag force, which allows simulation under conditions, where stable analysis was impossible with the previous method. Moreover, through validation, we confirmed that the proposed method can be applied to stable simulation under conditions that are impossible with the explicit method, and that the coarse-grained model can reproduce an original particles system.

Your impression & future plan

I am deeply honored to receive this award. I would like to express my sincere gratitude to Prof. Mikio Sakai for his continuous guidance. I would also like to thank everyone at Sakai lab for their advice and support. Encouraged by this award, I will continue to devote myself to my research and further improve my research.
