Abstrakt: Mixed convection in a highly supersaturated isothermal aqueous solution of potassium dihydrophosphate at the surface of a growing single crystal is investigated numerically. Unsteady solution flow at the feeder exit is simulated by specifying a time-periodic velocity distribution. It is shown that the concentration boundary layer is significantly homogenized as compared with a steady-state supply. The nature of the flow is investigated as a function of the distance between the feeder and the crystal surface. [ABSTRACT FROM AUTHOR]
