Autor: Shinichi Yuu, Kenji Ikeda, Toshihiko Umekage, kouki Nohara

Publikováno v: KONA Powder and Particle Journal, Vol 15, Iss 0, Pp 190-201 (2014)

For better understanding of gas and particle motion in a fluidized bed, we numerically solved the locally averaged three-dimensional Navier-Stokes equations and the Lagrangian equations for particle motion while taking into account the collisions bet

The Experimental Stress – Strain Rate Relationship of Granular Materials [Translated]†

Autor: Shinichi Yuu, Shigenori Kamimura

Publikováno v: KONA Powder and Particle Journal, Vol 11, Iss 0, Pp 191-198 (2014)

The flow of granular materials is important in the field of material handling. However, there are many unknown factors associated with the analysis of these flows. Constitutive relations (stress and strain rate relations) are needed to describe the f

Numerical Simulation of Constitution Relationship between Stress and Strain of Particulate Matters [Translated]†

Autor: Shinichi Yuu, Toshihiko Umekage

Publikováno v: KONA Powder and Particle Journal, Vol 25, Iss 0, Pp 270-279 (2014)

The relations between normal stress and normal strain and that between shear stress and shear strain, which are the constitution relationships, have been obtained in a simple and general particulate field by the numerical simulation using Distinct El

Mechanism of avalanche precursors in inclining granular layers using a continuum model obtained by discrete element method

Autor: Shinichi Yuu, Toshihiko Umekage

Publikováno v: Advanced Powder Technology. 32:2258-2267

How do large shear stress and stress ratio peaks, which are avalanche precursors, occur in granular layers in an inclining box and why do the precursors have periodicities? The answers are our main objectives. The large and small shear stress peaks w
