WebSep 2, 2024 · Crystallization In solid state chemistry, crystallization is a process that separates a solid from an aqueous impure solution in the form of crystals. It is the ability of an atom to increase the size of its nuclei and reach a critical cluster size. WebThe crystallization process modeling based on compartmentalization approach is implemented in MATLAB/Simulink. The same set of model equations and model parameters are defined in order to solve the conservation balance equations for crystallization process system (population, mass, etc.) for every compartment. However, spatial variations in the ...
