The effects of molten salt type, molten salt ratio, additive dosage and calcination regime on the regulation of the formation process and micro-morphology of flake alumina were systematically investigated, and its oriented growth mechanism was deeply elucidated. The results show that the sodium borate-sodium sulfate binary molten salt system can construct an excellent mass transfer environment for the dissolution-precipitation and crystal plane-oriented growth of alumina.

To account for viscosity effects, the Carreau–Yasuda fluid model is used to characterize blood flow. The micromixing performance of blood is examined across four Peclet numbers (90, 225, 360, and 450) and within a viscosity power index range of 0.3 to 0.7, corresponding to shear-thinning behavior. The numerical solution is obtained by decomposing the governing equations into three orders: zeroth-order, first-order, and second-order. The influence of channel material properties on micromixing efficiency is investigated by solving the fully coupled fluid–structure interaction (FSI) equations at the fluid–solid interface using the arbitrary Lagrangian–Eulerian (ALE) framework. The results indicate that an increase in viscosity generally weakens micromixing performance, except at a Peclet number of 90, where the trend is reversed. Additionally, as the Peclet number increases and viscosity decreases, the size of the generated vortices increases significantly. This study uniquely integrates the Carreau–Yasuda rheological model with ALE-based fluid–structure interaction, establishing a novel framework for blood micromixing.
