Abstract

A model that describes crystal growth and motion is presented. The model is based on concept of the direct simulation Monte Carlo and molecular dynamics methods and includes spherical crystal particles, nutrients species and a stationary liquid background. Nutrient particle motion and collisions are modeled using Monte Carlo procedures. Crystals are modeled as particles with a finite diameter and are allowed to grow after attachment collisions with nutrients. The momentum equation for crystals includes the action of gravity field and a viscous drag force. Preliminary simulations compare effects of gravity on the size distribution of the crystals and examine the settling characteristics of crystals under variable gravity levels.
