Crystallization mass transfer
WebJun 11, 2024 · While higher agitation speed improves mass transfer which improves local supersaturation, it can also induce particle breakage (Mazzarotta 1992), attrition (Biscans 2004), and agglomeration (Peña and Nagy 2015) which are often undesirable. An optimal mixing scheme design relies on experiments, modeling, and engineering experience. http://web.mit.edu/braatzgroup/mathematical_modeling_and_design_of_layer_crystallization_in_c_concentric_annulus_with_and_without_recirculation.pdf
