回転容器内における粉粒体流れ

The precession of a rotating vessel drives strong turbulence, and therefore strong mixing, of a confined fluid. We aim at applying this technique to the mixing of granular materials and conduct the numerical simulation by using the discrete element method to evaluate the mixing efficiency of this system. However, the precessing spherical vessel cannot drive effective mixing of granular particles regardless of the packing rate. In particular, when the rate is high, we need agitation to fluidize and mix the material.
