Abstract Numerical simulation of the hydrodynamics and mass transfer involved in the capping of large size Z-cut KDP plates has been performed. The variations of surface supersaturation with thin layer height, bulk supersaturation and rotation rate are analyzed. The results show that keeping still is very unfavorable for the growth of thin layer, a certain rotation rate should be applied to the Z-cut plate to increase the concentration gradient across the (0 0 1) face, thus making sure that thin...

Abstract A frustum is added to the platform used in the rapid growth of the potassium dihydrogen phosphate crystal on point seed, aiming at improving the supersaturation distribution on crystal surfaces. To evaluate the modification, numerical simulations of the hydrodynamics and mass transfer involved in the aqueous solution growth of KH2PO4 with the new platform have been performed. The variations of surface supersaturation with frustum inclination, rotation rate and crystal size are analyzed....

Abstract A novel solution-based crystal growth method, namely, the three-dimensional motion growth method (3D MGM) had been suggested by our team to effectively utilize convection for simultaneous enhancement of morphological stability and mass transfer. To evaluate this new method and link it to practice, numerical simulations of flow and mass transfer during large-scale potassium dihydrogen phosphate (KDP) crystal growth via this new method are carried out. The supersaturation field on the cry...

Abstract Computational analysis of the three-dimensional flow and mass transfer involved in the growth of KDP crystal with a planetary motion (PM) was conducted, in which the crystal executes an orbital revolution with a constant revolution rate during its self-rotation together with periodically changing the direction of crystal rotation. Compared with the conventional KDP growth method which conducts centric rotation (CR), this new configuration can avoid the sharp fluctuation of surface super...
