| Description: |
Summary The hydrodynamics and mass transfer of KDP solution in a crystallization chamber are studied for non-stationary regime of feeding with different inflow boundary conditions. The numerical investigation of the flows and the concentration field above the growing crystal, based on the solution of 2D and 3D non-stationary Navier-Stokes equations in Boussinesq approximation and mass transfer equations is performed. The high rate profiled monosectorial growth technologies (PMG) for aqueous soluble crystals have been developed due to the demand for large aperture nonlinear elements for power laser systems used in Inertial Confinement Fusion experiments. Profiled monosectorial crystal growth developed in the Institute of Applied Physics Russian Academy of Sciences (IAP RAS) is based on the growth in hard chambers with their cross section nearly equal to that of future elements. PMG enables to enhance the crystal growth rate 20 times as compared with traditional methods [1]. The main problems, arising while implementing this technology are connected with a morphological instability of growing crystal surface, caused by the interaction of growing surface with the rigid walls of the chamber, and organisation of material transport to the growing crystal. An important feature of the PMG developed in the Institute of Applied Physics RAS is the intensive feeding of the solution near the growing crystal surface. Creation of a homogeneous concentration field in the boundary layer is |
