電気抵抗の異なる2種の粉粒体の混合シミュレーション

抄録

In this report, the mixing mechanism of a binary system of particles with different electric resistance, group A and group B, was treated by the use of a two-dimensional model. Before mixing, the particles of group A and group B were arranged in a parallel circuit, as shown in Fig. 1, (c).
Accompanied with the beginning of rotation of impellar blades at an angular velocity ω_1-3, the particles belonging to 1, 2, 3 orbits began to move in their orbits at the same velocity as that of impellar blades, while the particles belonging to 4, 5 orbits had less velocities (ω₄, ω₅) than ω_1-3.
Together with the rotational motion of particles, the random exchange of positions of particles occurred. Thus, the resulting equation was as follows.
R=l×e^-kt×|∑a_i×sin(ω_i×t)|+(m-n×e^-kt)
where,
R: Total electric resistance
a_i, k, l, m, n: Constant
ω_i: Angular velocity
t: Time
