Spiky particles are constructed by superposing spheres and oblate ellipsoids. The resulting star particles (but nonconvex) are randomly packed by a sequential algorithm. The geometry, the conductivity, and the permeability of the resulting packings are systematically studied. Overall correlations are proposed to approximate these properties when the geometry of the particle is known.
尖刺状颗粒是通过叠加球体和扁椭球体构建而成的。由此产生的星形颗粒(但非凸形)通过一种顺序算法进行随机堆积。对所得堆积物的几何形状、电导率和磁导率进行了系统研究。当颗粒的几何形状已知时,提出了总体相关性来近似这些特性。
