| 總結: | Nanoparticles find its application in various fields. Apart from that nanoparticles tend to agglomerate which will
alter its physical and chemical properties, making it incompatible for the preferred application. To overcome this,
dispersion of nanoparticle is desirable which could prevent the agglomeration and provide a good dispersion
stability by retaining its properties. One of the most productive technique for the dispersion of nanoparticles is
beads milling process. In the other hand, experimental works to investigate the detailed hydrodynamics and flow
pattern in the whole system of bead mill is complicated and high cost. Numerical modeling offers a method to
predict the detailed hydrodynamics and flow pattern in the entire system inexpensively. The integration of DEM
for solid phase and SPH models for liqudi phase were carried out to simulate the mixing behavior in wet bead
mill. The effect of rotation speed of 1,200 and 1,800 rpm on the particle size distribution was discussed. For
rotation speed of 1,800 rpm, the particles are well dispersed resulting in a good dispersion stability. |
