On 7th December 2017, Mr. Kazuya Takabatake (D1), Department of Nuclear Engineering and Management, received Best Poster Award from the The 23rd SCEJ Symposium on Fluidization & Particle Processing.
It was given for the superior presentation at poster session at this symposium.

A large-scale non-spherical particle system often encounters in the industry. From a view point of calculation cost, the calculation of a large-scale non-spherical system was substantially impossible by using the existing methods. For the quality control and the optimization of industrial process, it was desired to develop a new calculation model of non-spherical particle system which is applicable to a large-scale problem. In this study, we developed a new rolling friction model in DEM and coupled the rolling friction model with DEM coarse grain model for a large-scale system. Besides, we applied SDF/IBM to this model as a modeling of an arbitrary moving boundary. Through some verification tests such as a rolling cylindrical tank and a die-filling, the adequacy of our new model and its applicability to DEM coarse grain model were both proved. We succeeded to establish the new calculation model of a large-scale non-spherical particle system.

It's my great pleasure to win this award. I really thank Prof. Mikio Sakai for his excellent supervision, and also all members of my laboratory. I will try to improve our researches.
