Summary:The dynamic behavior of a cystal particle moving in Bénard convection was in vestigated theoretically with a simplified model that simulates the state of a crystal particle in crystallizers. While the crystal particle circulates along the flow stream and passes through the supersaturated and the unsaturated regions alternately, both its size and its orbit change gradually. The motion of a crystal particle can be treated as a dynamical system in phase space whose coordinates consist of the particle diameter and the orbit diameter. The effects of system conditions such as the Rayleigh number, temperature and concentration on the behaviour of the crystal particle were examined in this phase space.
