A series of KDP crystals were grown by traditional growth method at different rotation speeds. Meanwhile, according to the actual growth conditions in the crystallization chamber, a three-dimensional model was developed. The dependence of temperature and velocity distributions on rotation speeds and the crystal size was numerical simulated by the finite volume method. It revealed that the flow velocities of the solution along the surface of KDP fastened as the rotation speeds increasing, which leaded to an increase in the crystal growth rate and the quantities of impurities reduced. Compared with low rotation speeds (9.0-40 r/min), high rotation speeds (55 r/min and 77 r/min) were to the benefit for the growth of KDP crystal.
