TLDR
In this article, the authors used a new model of micromixing, based on the spectral interpretation of mixing in the isotropic, homogeneous turbulent field to evaluate the influence of the intensity of mixing on the rate of precipitation and on the particle size of the product obtained in a stirred vessel with ideal macromix.About:

Chemical processing and micromixing in confined impinging jets
TL;DR: In this paper, the Damkohler number was used to correlate processing of a confined impinging jets (CIJ) mixer with a second-order competitive reaction set, and a scaling theory for the characteristic micromixing time, proportional to momentum diffusion starting at the Kolmogorov microscale, was presented.

Industrial crystallization from solution
TL;DR: In this paper, a review of crystallizer performance from a reaction engineering viewpoint is presented, focusing on the interaction between crystallizer fluid mechanics and residence time distributions with the physical chemistry of nucleaton and growth kinetics.

Mixing-precipitation model with application to double feed semibatch precipitation
TL;DR: In this article, a general mixing-precipitation model describing interactions between mixing of various scales (macro-, meso- and micromixing) coupled with the population balance for crystallization is presented.

Crystallization method to improve crystal structure and size
TL;DR: In this article, a continuous crystallization process is used to achieve high intensity micromixing of fluids so as to form a homogeneous composition prior to the start of nucleation.

Turbulent micromixing in chemical reactors - a review *
Jerzy Bałdyga,Ryszard Pohorecki +1 more
TL;DR: In this article, the effects of turbulent mixing of incompressible fluids in single-phase systems on the course of chemical reactions are discussed in detail: the fluid mechanical interpretation of turbulent micromixing (effect of fluid element deformation on the acceleration of molecular diffusion, engulfing of environment, inertial disintegration of large eddies and local intermittency) is presented.

TL;DR: In this article, the authors studied the kinetics of crystal growth of a number of sparingly soluble salts and found that the rate of growth of barium sulphate showed a third order dependence on concentration when the crystals were small.
