从理论上证明了颗粒群的体积分维数的物理含义,结果表明颗粒群的体积分维数可定量描述颗粒群的粒度分布宽度,准确反映了颗粒群填充三维空间的能力,并通过试验研究了颗粒群的体积分维数对滤饼孔隙率及比阻的影响规律。
The physical meaning of volume fractal dimension of particle swarm is theoretically proved. The results show that the volume fractal dimension of particle swarm quantitatively describes the particle size distribution width of particle swarm, accurately reflects the ability of particle swarm to fill three-dimensional space, and through experimental study The influence of volume fraction of particles on the porosity and specific resistance of filter cake was studied.
