Abstract : An example of the calculation of mixing flows in a solution crystal growth system is shown here. Solution crystal growth is an important means of producing a wide variety of organic and inorganic crystals. In these systems, a single crystal is grown from a supersaturated solution in which the material to be crystallized is dissolved as a solute. Macroscopic transport of solute molecules from the liquid solution phase to the faces of the growing crystal is almost wholly determined by fluid mechanics. Until recently, the extreme challenges posed by modeling flows within the 3D geometry of such systems has limited progress in understanding transport effects; the calculations shown here represent one of the first efforts to rigorously model flows within a solution crystal growth system.
