| Popis: | The turbulent hydrodynamics in a conventional operating crystallizer for growing kalium dihydrophosphate crystals is analyzed by physical modeling methods. The potentialities of an axisymmetric crystallizer, which has similar tools for stirring solution but is able to ensure controlled laminar hydrodynamic flows are considered. A combined mathematical model is formulated, which takes into account both the convective salt transfer in the crystallizer on the basis of solving the Navier–Stokes and diffusion equations and the kalium dihydrophosphate crystal growth on the basis of the theoretical model. A parametric calculation is performed to determine the effect of each mechanism of solution motion, including the directed solution outflow from a tube into the crystallizer and the rotation of crystal and stirrer. |
