Abstract

Equations are derived for the growth rate of ice crystals in the form of thin plates and prismatic columns suspended in a supercooled water cloud of given temperature. The effect of the fall motion of the crystal on its development is discussed โ€ in particular a criterion is derived for the transition from polyhedral to dendritic growth. Ice crystals grown in supercooled water clouds produced in large cold chambers reveal a double change of habit in the temperature range 0ยฐC to โˆ’40ยฐC. Experimental determinations of the growth rates of plate crystals growing at โˆ’2.5ยฐC and prisms at โˆ’5ยฐC are in fairly good agreement with the theory.

## Abstract The crystallization of ice in aqueous dextrose solutions is studied in an adiabatic continuous stirred tank crystallizer with a supercooled feed stream. The effective diameter of the ice crystals was determined for various values of mean crystal residence time, feed supercooling, magma
