Impact of Softness of Particles on Rheology of Dilute Granular Gases
Haruto Ishikawa, Satoshi Takada
We numerically and theoretically investigate how the softness of particles affects the rheology of sheared dilute granular gases. We find that the kinetic theory predicts the devia…
Drag of Two Cylindrical Intruders in a Two-Dimensional Granular Environment
Takumi Kubota, Haruto Ishikawa, Satoshi Takada
The drag of two cylindrical intruders in a two-dimensional granular environment is numerically studied by the discrete element method. We find the yield force, below which the intr…
Two-Step Discontinuous Shear Thickening of Dilute Inertial Suspensions Having Soft-Core Potential
Shuichi Sugimoto, Satoshi Takada
Kinetic theory for dilute inertial suspension having soft-core potential is theoretically investigated. From the analysis of the scattering process, the expression of the scatterin…
Particle flows around an intruder
Satoshi Takada, Hisao Hayakawa
Particle flows injected as beams and scattered by an intruder are numerically studied. We find a crossover of the drag force from Epstein's law to Newton's law, depending on the ra…
Drag acting on an intruder in a three-dimensional granular environment
Satoshi Takada, Hisao Hayakawa
The drag acting on an intruder in a three-dimensional frictionless dry granular environment is numerically studied. It is found the followings: (i) There is no yield force for the…
Scaling law of the drag force in dense granular media
Sonu Kumar, K. Anki Reddy, Satoshi Takada +1
Making use of the system of pulling a spherical intruder in static three-dimensional granular media, we numerically study the scaling law for the drag force acting o…
