| 摘要: |
"Collisional motion of inelastic rough spheres is analyzed on the basis of the kinetic
theory for flow of dense, slightly inelastic, slightly rough sphere with the consideration
of gas–solid interactions. The fluctuation kinetic energy of particles is introduced to
characterize the random motion of particles as a measure of the translational and
rotational velocities fluctuations. The kinetic energy transport equation is proposed
with the consideration of the redistribution of particle kinetic energy between the rotational
and translational modes and kinetic energy dissipation by collisions. The solid
pressure and viscosity are obtained in terms of the particle roughness and restitution
coefficient. The partition of the random-motion kinetic energy of inelastic rough particles
between rotational and translational modes is shown to be strongly affected by
the particle restitution coefficient and roughness. Hydrodynamics of gas–solid bubbling
fluidized beds are numerically simulated on the basis of the kinetic theory for flow of
rough spheres. Computed profiles of particles are in agreement with the experimental
measurements in a bubbling fluidized bed. The effect of roughness on the distribution of energy dissipation, kinetic energy, and viscosity of particles is analyzed." |
