Mpemba effect in a sheared granular gas with velocity-dependent restitution
Makoto R. Kikuchi, Yuria Kobayashi, Satoshi Takada
We investigate the Mpemba effect in a dilute sheared granular gas with a velocity-dependent restitution coefficient. Using kinetic theory based on Grad's moment method, we analyze…
Discontinuous change of viscosity in a sheared granular gas with velocity-dependent restitution
Makoto R. Kikuchi, Yuria Kobayashi, Satoshi Takada
We investigate the rheology of a sheared granular gas composed of hard spheres with a velocity-dependent restitution coefficient. Using kinetic theory, we derive the shear viscosit…
Kinetic theory of dilute weakly charged granular gases with hard-core and inverse power-law interactions under uniform shear flow
Yuria Kobayashi, Makoto R. Kikuchi, Shunsuke Iizuka +1
We develop a kinetic-theory framework to investigate the steady rheology of a dilute gas interacting via a repulsive potential under uniform shear flow. Starting from the Boltzmann…
Rheology of dilute granular gases with hard-core and inverse power-law potentials
Yuria Kobayashi, Shunsuke Iizuka, Satoshi Takada
The kinetic theory of dilute granular gases with hard-core and inverse power-law potentials is developed. The scattering process is studied theoretically, which yields the relative…
