Abstract Dispersion of liquids/particles is a key important requirement in a variety of applications including coatings and paints, cosmetics, healthcare, food, and pharmaceutical processes. In all these industrial processes high intensity of energy is required to overcome the adhesion forces or increasing interfacial surface area per unit volume, which is achieved by high-pressure homogenizers, ultrasonic-assisted devices, and high shear mixers (HSMs). In this paper, HSMs are critically reviewed based on their design and development, and applications (such as dispersion of nanoparticles, emulsification, and mixing) in recent years. HSMs are comprised of rotational (rotor) and stationary (stator) parts with a small gap in between. It is found that there is a significant influence of stator geometry on the uniform size distribution as well as energy dissipation. Though there is extensive work on hydrodynamics and mixing in HSMs are available however, still there is no specific scale-up/down criterion is available for HSMs.

高剪切混合器的设计和开发：基础、应用和最新进展

摘要 液体/颗粒的分散是包括涂料和油漆、化妆品、医疗保健、食品和制药过程在内的各种应用的关键要求。在所有这些工业过程中，都需要高强度的能量来克服粘附力或增加单位体积的界面表面积，这是通过高压均质器、超声波辅助装置和高剪切混合器 (HSM) 实现的。在本文中，基于 HSM 的设计和开发以及近年来的应用（如纳米粒子的分散、乳化和混合），对其进行了批判性评论。HSM 由旋转（转子）和静止（定子）部件组成，两者之间具有小间隙。发现定子几何形状对均匀尺寸分布和能量耗散有显着影响。尽管有大量关于流体力学和混合 HSM 的工作，但是仍然没有特定的放大/缩小标准可用于 HSM。
