Resistance functions for two unequal spheres in linear flow at low Reynolds number with the Navier slip boundary condition
Kengo Ichiki, Alexander E. Kobryn, Andriy Kovalenko
Resistance functions for two spherical particles with the Navier slip boundary condition in general linear flows, including rigid translation, rigid rotation, and strain, at low Re…
Behavior of fluidized beds similar to equilibrium states
Kengo Ichiki, Hisao Hayakawa
Systematic simulations are carried out based on the model of fluidized beds proposed by the present authors [K.Ichiki and H.Hayakawa, Phys. Rev. E vol.52, 658 (1995)]. From our sim…
Hydrodynamic effects in density waves of granular flows
Kengo Ichiki
Granular flows in a narrow pipe are studied numerically by the model taking account of hydrodynamic effects of fluid surrounding particles. In the simulations density waves are obs…
Dynamical Simulation of Fluidized Beds --- Hydrodynamically Interacting Granular Particles
Kengo Ichiki, Hisao Hayakawa
A numerical simulation of a gas-fluidized bed is performed without introduction of any empirical parameters. Realistic bubbles and slugs are observed in our simulation. It is found…
Statistical Theory of Sedimentation of Disordered Suspensions
Hisao Hayakawa, Kengo Ichiki
An analytical treatment for the sedimentation rate of disordered suspensions is presented in the context of a resistance problem. From the calculation it is confirmed that the lubr…
