Modeling of sintering regular packings of spherical particles

S3D Evolution is applied for structural-imitating modeling of regular packings consisting of spherical particles. Sintering is performed according to the diffusion-viscous flow mechanism. Data originating from the computations using the model corresponds with theoretical calculations and adequately reproduces results of physical experiments for the initial stages of microstructure evolution.

Fig. 1. Evolution of the model structures during the modeling of sintering the regular packing. Packing consists of 8 spherical particles. Sintering is performed according to the diffusion-viscous flow mechanism. Sections of the packing are colored with gray. t = 1,0[hrs] corresponds with one hour of real sintering time Fig. 2.
